IsDate

×V2.1Ø

Syntax -

       If IsDate <string expression>

               Where:

       <string expression> is a literal string or a variable containing a literal string.

Description:

This comparison operator is used to scan a literal string or a variable that contains a string value to insure that the string contains a date.  This comparison returns a TRUE condition the string can be coerced into a date.  This comparison operator can be used with either an in-line If (the original OLIE™ syntax) or a Block If.

Note:  This comparison operation does recognize the INVISION date format MMDDYY, this can lead to a non-date number being interpreted as a date.

Sample:

:CheckRecord

REM This will read the date from the Adhoc Copy to a variable and make sure it is a date

If EOF GoTo Xit

Read

Copy Date File 2 8

REM A valid line was found, so lets process it.

If IsDate Date GoTo Start

REM A valid line was not found, read next record

GoTo CheckRecord

:Start

REM start copying variables from file
