Really two questions:
How do I check if a variable is empty? Sort of like;
If !empty(tUsername)
// process here
Endif
Empty() is a Foxpro function that pops if what you are checking is empty. I
can¹t seem to find it¹s equivalent in revolution. Am I approaching this the
wrong way? And can I check fields the same way?
I suppose I could create an empty variable and just compare the 2? But is
there an easier way?
Next question; checking the existence of a variable? Now I know I can turn
on Strict Compilation (and I have) but I¹d rather have the assurance of
checking to see if a variable exist? Is this a non-issue in Revolution?
Thanks
