PICT
To perform a PICT check, specify the check item TYPE attribute as PICT. A PICT check allows you to specify a pattern used to validate the variable. The PARM1 attribute must have the value EQ. The PARM2 attribute contains the validation character string.
Here is an example where a PICT check in the socsec variable class
validates the format of a social security number:
<!doctype dm system>
<varclass name=socsec type='CHAR 11'>
<checkl msg=liba017>
<checki type=pict parm1=eq parm2='nnn-nn-nnnn'>
</checkl>
The conversion utility generates a PICT verification statement in the )PROC section.
