just a short followup to my earlier message about the $. line number
variable. when i enter a print statement as shown below, it prints the
correct line number (starting at 1), but still never enters the if()
structure.
for the sake of understanding how to correctly use this variable, i would
really like to get this code working. if i can't, then i will use one of the
workarounds that others on this list have suggested to me.
is there something special about the way the if() structure has to be
phrased, other than the way i have it?
thanks
