Evaluating Arithmetic Operators within Backticks
travs & brigmar, thanks for the suggestions. Yes I see what you mean about asking the shell to do the calculations, I hadn't really understood that before. And brigmar, that is what I had done (it works), but it results in longer code :P Miller, Wow! Even though your second improvement doesn't... -
Evaluating Arithmetic Operators within Backticks
Hm, I have already acknowledged that I am writing the code poorly. That was not my question, and in general I use good programming practices. I can see instances where having operators evaluated properly inside backticks would be useful and convenient even if I were not trying to minimise the... -
Evaluating Arithmetic Operators within Backticks
Hello. I am relatively new to perl, and I am having a problem involving the evaluation of arithmetic operators enclosed in backticks. From within my perl program, I call another perl program, using the following lines of code: @n=@ARGV; map system("perl other.pl ".($n[0]-$_)." ".($n[1]-1)."...
