Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

This is MMBasic 5.3 on both MZ and MX processor.

The NEW command seems to clear variables but does not de-allocate the space.

What am I missing?

I believe you re-allocated memory when you printed the variable a to show it had been cleared. Try using MEMORY immediately after doing a NEW instead.

Unfortunately I don't have a 'mite handy to test with at the moment.

This is correct! It has thrown me a few times too

To see this affect - type a few more PRINT x statements (replacing x with different 'made up' variable names) and then type MEMORY again. You will see the variable count increase for each unique variable you just typed PRINT x for.
