TEXT Function

Description

$TEXT(entryref)

The $TEST() function returns the text of the source for the line specified in its argument, allowing this text to be assigned to a variable. The complete line will be returned, including label, commands, and comments.

If $TEST() cannot access the source for the current object or the source that is found doesn’t match the object in use, $TEXT() will return the empty string.

Parameters

entryref specifies the label, offest, and routine name of the line that $TEXT() returns.

If the label and offset are not in the routine, $TEST() returns the null string.

If entryref specifies an offset of zero or no offset from the beginning of the routine, the routine name is returned.

If entryref does not specify a routine, it is assumed that the routine is the current routine.

An extension to $TEST() allows negative offsets, however these offsets must be preceded by a + sign (ie LABEL+-1), but if this causes the line to be before the zero line, a run-time error occurs.

Examples

FOR I=1:1 SET J=$TEXT(+I) QUIT:K=”” WRITE !,J

This command uses the $TEXT() function to write all of the source for whatever the current routine is.

$TEXT(+0)

This command returns the name of the current routine.
