I'm a long time Crystal report writer trying to convert reports to WebFocus in which I have virtually no experience. I'm doing alright but am stuck with one part of the formula. In Crystal I have:
if(isnull({geolocn_code})) then true else ({campuscode1} = "H")
How could I reproduce this in WebFocus?

its the concept of MISSING
Do you have manuals or can you download them?
For example,when you create a variable, you can specify this MISSING condition
DEFINE FILE whatever
MYVAR/I8 MISSING ON = IF sometestcondition THEN somevalue ELSE MISSING;
END
When you display this variable, it will appear as whatever you have your NODATA setting set to, which is usually a dot, by default. The command is SET NODATA = '.'
This a quite a valuable feature, you would probably enjoy reading about it in the manuals.
Congratulations on moving to focus. you'll enjoy it.
