Hi,
I keep seeing the statement (something like):
IF variable
do something...
ENDIF
Rather than (as I would do):
IF variable=1 (or whatever)
do something...
ENDIF
Could someone explain the logic of this, please?

The way I understand it is the IF variable statement (without the = sign) is asking if the variable is some non-zero value.
when you have IF a =1 that will only be true for when a is = to 1.
when you have If a is true for any value except zero
Sapero has the source code for the parser; if I'm wrong he can tell us exactly how it works.

I only use that form for Boolean variables. Some folks use it to detect zero which I think can be confusing.
Hello,
That's great - so if I think the variable should be something other than zero,
I can just use the short form of IF
Many thanks for clearing that one up,
Brian
