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.
