RE: QMQRY question

[Buck Calabro <mcalabro@xxxxxxxxxxxx>]

Dennis,
You've done 99% of the detective work, and are almost there!

Think of an *ISO date as a character field (even though it's not.)  The
variable that you need to pass must look like '1999-01-01'  If you
dump/debug the failing version, you will see 1999-01-01 - no quote marks.
In order to include the single quotes inside your variable, you need to
place two of them side-by-side.  In order to tell the CL program that you
are specifying a character literal, you need to enclose the lot inside
single quotes.  This will result in a silly-looking triplet of single
quotes: '''1999-01-01'''

I think of it this way: One tick mark to denote "begin char literal", two
tick marks to denote "single quote", then the literal I need, then two tick
marks to denote "single quote", then one tick mark to denote "end char
literal"  

This is generic to dealing with any character string, not just *ISO format
dates.
I hope this helps.
