CHKDAT CHECK DATE TAADATB
The CHKDAT command provides a method of performing some validation
against a date field. Not only must the date be valid, but optional
parameters allow you to perform some range checking on the value
A typical command would ensure that the date entered is within 365
days after today.

The data must be entered in job format.
Command parameters *CMD

job format (e.g. MMDDYY).
DAYLORNG The low range in days from the current date. For
example, if the date should not be in the past,
enter 0. The default is -365 days meaning the date
must be within the last year. You may also enter a

example, if the date should not be in the future,

with *NO as the default. If *YES is entered, the
