I wrote a function that closes all tables in all work areas, except for the ones I pass in a parameter list. I use a for loop:

for i = 1 to 255


But I want to know how to test for the maximum number of workareas, depending on the version of foxpro, or whatever other variable determines it, so i can change it to:

for i 1 to lnMaxWorkAreas

I seem to recall that a function or system memory variable exists for this, but I can't seem to find it in the help.

TIA
