in thread Application Design Issue

I am creating step1_file that indicates that step1 has been executed successfully.
If any error comes then that step${n}_file will not be created.
How this to implement in main script.
Are you indicating something like, create label and then use GO TO ?

    I would read in (with glob) the step_X_done file. Read its number, or 1 into a variable $already_done

    for my $todo ($already_done .. $final_step){ do_step1() if $todo == 1; do_step2() if (-e step_1_done);
    then wrap the code for each step in separate subs.

    Now you can manually delete a "step-file" to have the job start from scratch, or at some spesific step, if you ever need that.
