Ahh, I think your do & while need to be matching o words.
Thanks Jeff & Gene,
I modified the script as below but now I'm back to one of the original
problems - it won't load because it says "near line 49 ...... unknown
word where unary operation could be" (Line 49 is my line numbered
N0400). This is at the call to the first subroutine, o100, and the only
way I could clear it before was to take out the o100 before the endsub -
but then the program wouldn't run. I tried isolating the problem by the
rather crude method of simply temporarily deleting each line of code in
turn to see if the error would clear or at least move on to the next
error and this was how I identified the endsub line number to be a
problem, however, I've just tried the same again and it has no effect. -
now I'm stuck again although there may be just a glimmer of light from
Gene's comment - is the error that the do/while loop in the main part of
the program should be numbered differently and have both lines preceded
by an Oxxx number? If so would that then be another subroutine which
would need calling from a main program consisting just of calls? Boy,
this stuff is fussy!!
