The ZX Spectrum does Not make a difference between capital or lower character variable names. A normal variable can be severall letters long, any DEF FN, FOR/NEXT, DIM (STRING or DATA) array name is a single letter variable name. None of these are special variables. for 128k zx spectrum matters that In REVERSED SENSE some variable names are IMposible becouse of the tokenized form in the 48k basic eg 'not' will be NOT !!!! |
