SAVE "xxx" CODE START, LENGTH
SAVE "xxx" SCREEN$ [Note: This is the functional equivalent of SAVE "xxx" CODE 16384,6912 ]

LOAD "xxx" CODE
LOAD "xxx" CODE START
LOAD "xxx" CODE START, LENGTH
LOAD "xxx" SCREEN$

VERIFY "xxx" CODE
VERIFY "xxx" SCREEN$
The above commands work in a manner identical to Sinclair Basic.

1
SAVE "xxx" DATA <varname>( )
This behaves like the original Sinclair BASIC, but here you can save/load/verify not only arrays, but single variables. Parenthesis can be omitted (in Sinclair BASIC they were mandatory). You can also use LOAD/VERIFY with this.

1
 SAVE "xxx" DATA

With no varname saves ALL the entire user variable area plus the HEAP memory zone. That is, it saves the entire program state. You can also use LOAD/VERIFY with this.

Remarks

  • The save command should save bytes in a format that is 100% Sinclair BASIC Compatible
  • For LOAD and VERIFY, when a R-Tape Loading error occurs, the program will not stop. You have to check PEEK 23610 (ERR_NR) for value 26. If that value exists, then the LOAD/VERIFY operation failed.
  • LOAD/SAVE/VERIFY can be interrupted by the user by pressing BREAK/Space, which cancels the operation (signaling the break in ERR_NR and returning). If you want LOAD/SAVE/VERIFY to be interrupted and exit also your program (returning to the ROM Basic), compile with --enable-break flag.
  • When using LOAD "xxx" DATA... you won't see the message "Number array:" or "Char array:", but "Bytes:" instead. This is because ZX BASIC always uses bytes (LOAD/SAVE ... CODE) for storing user variables (ZX BASIC is machine code, so the idea of BASIC variables doesn't apply).
