in thread Number of times I've used goto in Perl

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!!

    Why not in main wrap blocks of calls in eval blocks and die when you hit errors?
