If you do it with a process procedure, you can set the filter in the
template. If you have a had-coded loop, you will simply have to accommodate
it in the logic:

SET(File)
LOOP(File)
NEXT(File)
IF File:Column=SomeValue
Do something here
ELSE
Do something else, or nothing
END
END

Hi "don zaragoza"
I guess this example should work if ABC:
! Showing a total of all positive numbers.

GLO:TOTAL = 0 ! Muy importante
SET(Filename)
LOOP UNTIL EOF(Filename)
NEXT(Filename)
IF A:TALL > 0 ! Filter start
GLO:TOTAL += A:TALL ! Adding all positive numbers
END ! Filter end
END
