This document covers the following topics:
Return a list of all variables appearing in a document text. You can only access Txt and Cnf documents.
Variables returned in the Variable-table are not duplicated with each call. For example, if the part of the text which is currently being processed contains &HELLO twice, only one HELLO is returned. However, when this subprogram is called iteratively, and if &HELLO appears again in the text, it is returned in the new Variable-table.
Con-form system variables are not returned.
Note:
In the document text, the characters after the variable character
(default: &) must be alphanumeric (the underscore character (_) can also be
used), otherwise the variable is not returned in the Variable-table. Thus,
Con-form system variables (e.g. &$PN) are not returned.
| Parameter | Format | In | Out | Remarks |
|---|---|---|---|---|
| Return-code | N2 | O | X | Input -1: no ET. |
| Cabinet | A8 | R | The cabinet in which the document is stored. | |

| ISN | P8 | R* | The ISN of the document which contains the variables. Either ISN or Document-name, not both. | |
| Start-value | A32 | O | The name of a variable. If specified, this subprogram returns variables starting with the first occurrence of the Start-value. If a start value is not specified, this subprogram starts at the beginning of the document text. | |
| Number | N2 | O | The maximum number of elements that are returned with each call. When you do not specify a value, or when you specify a value greater than 20, the default value 20 is used. | |
