fumbling first questions

[Andrew Lindsay]

Just a suggestion, if your code/program is not something that is trade secret, it may be beneficial to share it?  I know that I have had lots of help with the guys on this forum and at Powerbasic in helping to optimize code.
I've done a little bit of demangling too to convert from Gosub-Return to structured code.
And how knows, someone may have already solved the problem you're seeking a solution for.
