USE Command

Hello, just wondering if anyone found out how to use the USE command and how to structure it. The :3

Thx×

Seems useless as the programs are already executable without using "USE" From the doc: "Makes a program in the specified program SLOT executable" Example USE 2 I can just call EXEC 2 without USE 2 to and it works anyway.

EXEC runs the entire code of another slot from the top, and as you said, can be used without USE. After a USE, though, you can jump to specific places in the other code with GOTO or GOSUB, or call a function from the other block, to use it more selectively. You can jump to labels in another program slot with, for example GOTO "n:@LABEL" where n is a slot 0-3. To do this, you have to USE n first. You can also access functions that are defined in a COMMON DEF block in another slot as well, but you have to USE that slot first. It seems that when you run a program, SmileBASIC searches it for DEF blocks and loads them into memory; if you include a USE command in your program, it also searches the slot you USE'd for DEF blocks and loads them as well (before executing any other code, I think). Also, you can write lines of code to another PRG slot, with instructions like PRGEDIT, PRGSET, etc. After you write lines of code in slot n, you have to USE n to alert the system that that code has changed, and then you can access that code with EXEC, GOTO, function calls, etc. etc.

Cool thx

Yea, I use USE when making libraries. PRG 0:

USE 1
SET_UP_GAME
PRINT "I just used slot 1"

PRG 1:

COMMON DEF SET_UP_GAME
  PRINT "Apple juice"
END

Thanks?
