I've looked at the official manuals and the homemade manuals and notebooks and I understand what their syntax examples are saying but I still need to see a sample program.
Theirs 4 different types:
1a) START-NEXT
1b) START-STEP
2a) FOR-NEXT
2b) FOR-STEP
3) DO-UNTIL-END
4) WHILE-REPEAT- END
Does anybody have a JPEG of their notes on this or program(s)they may have written. Just a simple simple program that works would be a good start. I've always had trouble figuring this out. I can put this in my collection of notes and homemade manuals. Everything I have collected is available in my folder under downloads and can be downloaded directly from this site.
Please help.
