HP-71B BASIC Question

[Sylvain Cote]

Valentin, criticize or nitpick at will, you are welcome.
Valentin, Tom & Jean-François, you made me realize that I was asking too much from the BASIC language.
I have been spoiled from all the languages/paradigms that I have used since the 1980's and I have difficulty going back to a world that does not even have functional decomposition.
I am currently writing a HP-71B BASIC program that does low level HP-IL control and while the code grows I was trying to bring order to chaos.
I will refactor the code to remove all the CALL/SUB and replace them with GOSUB/LABEL.
I will also need to seriously manage variables names/usage because they becomes global.
Thank you!
Sylvain
