The Spanish Inves/Investronica version of the 128k Sinclair Spectrum had a rather different ROM from the English 128k Speccy.
Error messages were in Spanish, there were extra letters and punctuation replacing some symbols, it didn't have the menu at boot-up, it had a different BASIC editor, etc.
It also had some extra commands:
The only one I can figure out how to use is
EDIT which is just followed by a decimal line number
All of the others I try with one, two, three decimal parameters, separated by commas or not, surrounded by parentheses or not, and I always get the same error message no matter what I try:
2 VARIABLE INDEFINIDA, 0:1
Also I can't get the editor to accept any of them as part of a line of BASIC code. I assume they're all intended to be immediate mode commands and can't be used in BASIC programs by design. But without seeing a guide I suppose I can't be 100% sure.
I've spent hours Googling in English and Spanish and can't find a guide of how to use them. (I'm aware that
WIDTH is broken and undocumented but still want to try it.)
Does anyone know how to actually use them?
