I guess that "missing" doesn't = " ". If it's a relational table it
certainly isn't.
I can't remember if there's a select for "missing" but you can do a range
check.

Hi

Could someone explain this to me.  I must be missing something.

I am accessing a table where there is some missing dates in a character
field (HISTORY-DT).  I wrote a simple check to see if the first character
was blank, yet the report found nothing.  I know there are definitely
records in the table that correspond to the select I used.  How can the
following not be working:

> access history
> define d-test char*1 = history-dt[1:1]
> choose rec-loc "VANDAM"
> REP REC-LOC HISTORY-DT D-TEST
> GO
