Tips for Saving Memory
1) Consider replacing GOTO 50 (for example)
In a program, statements such as GOTO 50, use seven bytes per digit.
You can actually change this to GOTO VAL "50" - here, you only use 1 byte per digit as the number is stored as a string.
2) Consider defining variables used by your program directly.
For example, if your program starts with:
10 LET A=50
20 LET B=100
30 LET C=1
You can add a SAVE line at the end of the program, followed by a RUN command to run the program after saving and loading.
before you SAVE the program ensures those variables are set up on loading the program.
You actually save 49 bytes in total !!
