Syntax


Assignment statement syntax

>>-ISREDIT--(var1,var2)-- = --DISPLAY_COLS---------------------><

var1: The name of a variable containing the column number of the first data column visible to you. The column number is a 3-digit value that is left-padded with zeros. If the variable is VDEFINEd in character format, it should be defined with a length of 5. The returned value is left padded with zeros. For compatibility with previous releases of ISPF, a length of 3 or 4 is allowed in cases where no data loss will occur.
var2: The name of a variable containing the column number of the last data column visible to you. The column number is a 3-digit value that is left-padded with zeros. If the variable is VDEFINEd in character format, it should be defined with a length of 5. The returned value is left padded with zeros. For compatibility with previous releases of ISPF, a length of 3 or 4 is allowed in cases where no data loss will occur.

Description

Columns that contain sequence numbers are not considered data columns. Do not use this assignment statement in initial macros because the columns displayed are not known until the data first appears. See Referring to column positions for more information.
