Syntax for all commands: command <variables> [!option] [!option := a|b]
[ ] : optional specification.
{a|b|...} : indicates alternative choices
<...> : indicates user specified name/identifier

If you are in doubt of when to use double quotes "" and when not, the rule is:
Use "..." for all external references (e.g. "file names.ext") or assignments of text values ( e.g. set "COMMANDLOG" := "ON")
Double quotes are NOT needed for variables, defined value labels, dataset names etc

• <filename> An optional filename may be given. The file format is detected based on the file extension (rec|csv|epx|epz|dta). If no filename is given the open file dialog is started.
• <expression> An optional expression (instead of <filename>) that resolves to a string containing the filename. E.g. a concatenation of strings or a global variable. (see examples)
• !force Will force reading a locked epx/epz file
  Note: Use with caution since the project may be used by someone else
• !c Will close current project. It is only needed if you have changed the content of the previous project. E.g. data, labels, variables, valuelabels, etc.
• !d := "<single character>" Will force the delimiter used when reading .txt/.csv files
  This option is only valid when importing delimited files. During import the delimiter will be validated and if the structure of the file does not fit with the selected delimiter, it will be rejected.
  If no delimiter is set for importing delimited files, the program will guess which delimiter is used based a fixed set of possible delimiters.
• !q := "<single character>" Will force the character used for recognizing quoted strings when reading .txt/.csv files.
  This option is only valid when importing delimited files. If quotechar is set to empty/nothing (e.g. !quote := "") then complete content of the file is used in guessing/validating delimiters.
  If no quote characters is set, the default " (double quote) is used to identify strings.
• !vn := {true|false} Will force the program to read first line in a .txt/.csv file as either variable names or as data.
  true forces it to read first line as variable names, with no regards to the actual content.
  false forces it to read first line as data, with no regards to the actual content.
  If the option is not used when reading delimited files, the program will guess based on the content if first line is data or headers.

  Note: In files with all string data and where first line is known to be variable names, the program has a high probability of guessing incorrectly on whether first line is headers or not. In such cases please use this option to ensure correct reading of data.

• !pw := "<string>" If you use this option with a password protected file (either .epx/.epz or .rec file) reading will occur directly, otherwise you will be prompted for a password.
• !login := "<string>" If a EpiData project in an EPX/EPZ file has Extended Access enabled, you will be prompted for login with a password and a username. With this option, the file is opened with the supplied login. A password for that user may be supplied with option !pw := "<string>"

• <filename> An optional filename may be givin. The file format is detected based on the file extension (epx/dta/etc...). If no filename is given the save file dialog is started.
• <expression> An optional expression (instead of <filename>) that resolves to a string with the filename. This can be e.g. a concatenation of strings, a global variable or something else. See read for examples.
• !output [:= "html | text"] Instead of saving to the project, this options saves the output to a file. If no format is specified (text/html) then the current output format is used.
• !replace Overwrite existing file
• !format := "{stata|epidata|csv} Save the project as a specific type. Note: This will ONLY change the content. The user must secure correct extension for a given type.
• !force Will force overwriting a locked epx/epz file
  Note: Use with caution since the project may be used by someone else
• !d := "<single character>" Will force the delimiter of values/names used when writing .txt/.csv files
  This option is only valid when saving delimited files. The default value is "," (comma)
• !q := "<single character>" Will force the character used for writing quoted strings.
  This option is only valid when saving delimited files. The default value is " (double quotation mark)
• !version := <integer> Specify which stata version to save the data as. Accept values range from 4 -> 14, default is 14
• !vn := {true|false} If true the first line in the .csv/.txt file is the variable names. Default value is "true"
• !dated := "<single character>" Will force the character used for writing date delimiters. Default value is "/" (slash)
• !timed := "<single character>" Will force the character used for writing time delimiters. Default value is ":" (colon)
• !decd:= "<single character>" Will force the character used for writing decimal seperators. Default value is "." (dot)
• !nl := "<single character>" Will force the character used for writing newlinex. Default value is that of the operating system:
  Linux: #10 MacOS: #13 Windows: #13#10
• !memonl := "<single character>" Will force the character used for writing the linebreaks from a memo variable. Default value is " " (space)
• !fixed Forces the writing of the .csv/.txt in a fixed format, where the length of each variable is used to specify the length of each column.
  Using !fixed ignores the use of the option !d
• !bom This options adds the UTF-8 Byte Order Mark (wikipedia) to the .csv/.txt file.

Add observations after all observations in current file

• !fn := <filename> Append this file - without !fn the file open dialog is shown.
  All known file types may be used and all options from read associated with reading of data can be used too.
  e.g. !d or !h options for reading csv files.
• !ds := <dataset> Optional! Specifies which dataset to use from the external file. It is only needed
  if the external file contains multiple datasets.

See variables on using referenced variables for this command

Merge the current data file with another dataset file based on key variable(s). The result is a NEW dataset which is added to the top level of the project.

• !fn [:= <filename>] Merge with a dataset in this file. Without !fn it is assumed that current used dataset should be merge with a related dataset.
  If no <filename> is provided then a dialog is shown to open the external file.
  All known file types may be used and all options from read associated with reading of data can be used too.
  e.g. !d or !h options for reading csv files.
• !ds := <dataset> Optional! Specifies which dataset to use. It is only needed if the multiple datasets exist (either as related datasets or in external file).
• !combine All non-missing values in the external dataset replaces all MISSING values for common variables
• !update All non-missing values in the external dataset replaces ALL values for common variables
• !replace All values in the external dataset replace all values for common variables
• !table The external file is used as a lookup table.
  E.g. to add person information to a file with clinical results
• !r Specify a different name for the resulting dataset. Default naming is a concatenation of the two used datasets

After merge the variable mergevar indicates source of information for each observation (records).
mergevar is defined with variable labels for these values:

• 1: In main dataset only
• 2: In merged dataset only
• 3: In both datasets

Create a new global parameter variable with a given type and optionally assign the value given in an expression.
The global variable or parameter has only one value, whereas a standard variable has one value for each observation. The global variable type and expressions type must be compatible otherwise an error will occur.
Global variables can for most parts be used like as a regular variable, but they cannot be evaluated as a vector.

If the name is post-fixed with square brackets [...], then a global vector is created, where each entry can be individually addressed using e.g. "g[3] := 20". If a value is assigned when creating a new global vector all entries of the vector will have the same value!

See variables on using referenced variables for this command

Create a new value label set with a given type (boolean not supported) and assign at least one (value, label) pair. Each (value, label) pair will be added to the newly created set. The datatype of the value MUST match the defined datatype for the value label set itself.
It is not possible to create an empty valuelabel set.

Note: An empty set will restrict data entry to system missing only!

• !m := <value> Marks the given value in the value label set as missing. If the value is not part of the (value, label) pairs or the datatype does not match an error will be reported.
  This option can be used multiple times with different values.

Drops all data within current select from memory. Save the data first if you wish to keep any changes.

• !del Drops all observations marked for deletion. Note: Make sure to test whether this creates a problem in a related dataset with the check command

Work with selected observations (subgroup of data)

Select requires a command or a begin ... end segment following the expression. After the command(s) are executed, the dataset is no longer reduced.

It is possible to make nested selects which will combine the selects. Example:

This is a "flow" control statement - which will evaluate logical_expression once and execute the command(s) following then when the logical expression is true. Note: This statement is not normally used to change values of variables (see the example below). The else clause is optional and is only executed if evaluation of the logical expression is false.
- for complex logical expressions, use parentheses for clarity.
Note: The if is changing flow of programming NOT values in variables unless the logic in the if ... ; defines this.

Note: The flow control of "if ... then .... was completely different in EpiData Analysis Classic v2.2.

Loops through the integer values from start to end either in ascending order (to) or descending order (downto).
If the values are in the wrong order (e.g. start value > end value, and the order is ascending) then the statements are not executed.
<var>: Must be global variable (single or vector) and integer datatype!
The result of <start value> and <end value> must be an integer value

See variables on using referenced variables for this command

Loops through the values one by one, assigning it to <var>

The only restriction in this loop is that the datatype of <var> and <value> must be the same!

See variables on using referenced variables for this command

Reorders the variables specified. This can be used to place specific variable together and used with variable expansion

• !before := <var>Places the variables before this variable
• !after:= <var>Places the variables after this variable
• !lastPlaces the variables at the end of the list

If no options are specified, the default is to place the variables before all other variables in the list. Use F3 or "list variable" to show the current order of variables.

See variables on using referenced variables for this command

Show result of an expression. It is posible to use all types of variables (standard, results or global) in the expression.
Note: if you are using standard variables it is possible to change a given specific observation with [x] (x is an integer).
Examples:

It is also possible to assign a value to individual entries of a variable:

If you specify a conditional (depend) rule based on other variables the change only occurs for the subgroup defined by the select statement:

Referenced variable may also be used in the expansion. These will be evaluated before the expansion!

This can be combined with eg. indexing of a variable. Using some of the builtin result variables like $dataset and $variable:

The Variable inside the @{..} may itself be another reference (with or without index), making it possible to combine multiple levels of references.

Run all pgm's in a given directory (folder) to verify function.
- suited for testing of correct estimation etc.
If no path is given, a dialog is shown to select the working directory.

Execute sequence of commands saved in a pgm file
- without parameters, the open file dialogue is started

Complete reset of all parameters of the program!
This is almost equivalent of doing:

• String functions
• Arithmetic functions

• Date functions
• Logic functions

• Conversion functions
• Test and special functions

• Operators
