The DISPLAY_LINES assignment statement
retrieves the relative line numbers of the first and last data lines
that would appear at this point if the macro ended, and places them
in variables. Other non-data lines might be on the display. Do not
use this assignment statement in an initial macro because the lines
displayed are not known until the data is first displayed.
Syntax
Assignment statement syntax
>>-ISREDIT--(var1,var2)-- = --DISPLAY_LINES--------------------><
- var1
- The name of a variable containing the relative line number of
either the first visible data line or block of excluded lines if the
macro ended at this point. The relative line number is a 6-digit value
that is left-padded with zeros. If the variable is VDEFINEd in character
format, it should be defined with a length of 8. The returned value
is left-padded with zeros. For compatibility with previous releases
of ISPF, a length of 6 or 7 is allowed in cases where no data loss
will occur.
- var2
- The name of a variable containing the relative line number of
either the last visible data line or block of excluded lines. The
relative line number is a 6-digit value that is left-padded with zeros.
If the variable is VDEFINEd in character format, it should be defined
with a length of 8. The returned value is left-padded with zeros.
For compatibility with previous releases of ISPF, a length of 6 or
7 is allowed in cases where no data loss will occur.
Return codes
- 0
