Desk Checking and Sub Routines (1 Viewer)

[DJGerber]

I've got no problem doing a desk check on a given algorithm, just rule up a table with a column for each variable and a column for output and navigate my way throught the code - BUT, what happens when I reach a sub routine? (ref: HSC 2001, Q21). How do I seperate local and global variables and local variables that share the same name across sub routines - what a mess.

Any ideas?
