Hi Corona,
I understand what you're explaining me.
From time to time I do Excel macros and shell scripts, in both scenarios, by far I'm not an expert, but in Excel using that feature,
for instance, I can find the errors faster and/or improve a bad loop.
I only was wondering if in shell that feature exists because I know even less than Excel Macros and I need more
time to find where the error is, or how to know how it goes the code even it has no errors.
Thanks for help.
