Bless me father for I am about to sin....
I may have found a use for the goto but I thought
I'd would consult with the elders prior to taking
the plunge!
I have one large perl script that drives a large data
loading process every night. The script has a "main"
subroutine that has roughly 30-40 steps - here's a snippet:
sub main { ##>> 01001000:set output &set_output; ##>> 03001000:database up &database_up; ##>> 04001000:prior status &prior_status; ##>> 06001000:delete log records &delete_log_records; ......... the "&" labels in "main" naturally call subroutines down in the body of the script. If our load process fails I want a way to "goto" the failure point in the script and continue processing by passing in a parameter that represents the step from which I'd like to continue. I can't think of another way of doing this with out rewriting the whole blessed script. Help O great ones!! Grasshopper
