CONFIG CASE UPPER|LOWER|TITLE
The CASE setting will change the case used for listing command and function names when using the LIST command. The default is TITLE but the old standard of MMBasic can be restored using CONFIG CASE UPPER.
The CONFIG command differs from other options. It permanently reconfigures MMBasic and it only needs to be run once (ie, the setting will be remembered even with the power turned off).
The power must be cycled after changing a setting for it to take effect.
