Changes since v.1.2.3
===================================
- ! Detected and fixed potential memory leak when using @operator
- LOAD/SAVE/VERIFY features added!
Notes:
- SAVE "xxx" CODE ... and SAVE "xxx" SCREEN$ work as in the original Sinclair BASIC. The same applies for LOAD & VERIFY.
- For LOAD & VERIFY, when a R-Tape Loading error occurs, the program doesn't stop. You have to check PEEK 23610 (ERR_NR) for value 26. If that value exists, then the LOAD/VERIFY operation failed.
- At this moment, LOAD/SAVE/VERIFY can be interrupted by the user by pressing BREAK/Space, which exits the program and returns to the ROM BASIC. This can be changed in the future to behave like the previous point (signaling the break in ERR_NR and returning).
- SAVE "xxx" DATA <varname>( ) behaves like the original Sinclair BASIC, but here you can save/load/verify not only arrays, but single variables. Parenthesis can be ommited (in Sinclair BASIC they were mondatory). You can also use LOAD/VERIFY with this.
- SAVE "xxx" DATA with no varname saves ALL the entire user variable variable área plus the HEAP memory zone. That is, it saves all the program state. You can also use LOAD/VERIFY with this.
- When using LOAD "xxx" DATA... you won't see the message neither "Number array:" nor "Char array:", but "Bytes: " instead. This is because ZX BASIC use always bytes (LOAD/SAVE ... CODE) for storing user variables (ZX BASIC is machine code, so BASIC variables are nonsense).
