Hi Wendy,
If you remove @AM, @VM, and spaces by changing them to null values with
the CONVERT function, then if the variable has anything left in it, you
have a non-empty value.
JUNK=TEST.1
CONVERT @AM:@VM:" " TO "" IN JUNK
IF LEN(JUNK) GT 0 THEN
PRINT "TEST.1 IS NOT 'EMPTY'"
END ELSE
PRINT "TEST.1 IS 'EMPTY'"
END
Just be sure to use a "junk" variable and don't CONVERT the actual
variable.
HTH,
BobW

Subject: [U2] Is a dynamic array "empty" or not?
I'm probably missing something obvious here...
What can I use to evaluate the "emptiness" of these arrays, so that 1
and 2 are considered empty and 3 is not?
TEST.1 = @VM:@AM:@VM:@VM:@AM:@AM
TEST.2 = @VM:@AM:' ':@VM:' ':@VM:@AM:' ':@AM
TEST.3 = @VM:@AM:' ':@VM:'zzz':@VM:@AM:'abc':@AM
Thanks!
Wendy Smoak
