Alan,Gordon,List,

The real advantage to having subPROGRAMS rather than subroutines (and
calling them by their Onnnn program number with an M98 is that ANY
program can 'become' a sub-program at ANY time! It just has to be in
the control memory!
And it can just as easily be removed and replaced without changing
the orig. program (just rename the 'improved' program to the Onnnn
number 'called by' the M98!)

Hope this helps.

P.S. Smoke, And in this way, the sub-program is not at the beginning,
end, or middle! It is just there, like any other program, waiting to
be used OR perused :-)
