Or what I hope people will find useful.
I have been having read and write memory errors while generating or
trying to change captions for commandbuttons I have generated in a
macro that loops so I can generate multiple commandbuttons
From reading other threads in this forum I have set every variable
used to either Nothing or Empty when finished with it and it did work.
My macro's run like a dream.

I have posted this as once you seem to get in the trap of getting a
memory error, it is very difficult to pin point the problem.

I will certainly ensure I empty all variable when finished with them
in the future.

Has anybody else got any useful must do's to prevent memory errors ?
