Help please I dont understand

[jay-51]

Hello again

please,i dont understand this
I have a MBB with atom pro 28, I made the following code:

main index2 =3 for index=0 to 3 gosub MOVI(index) nap index2 next
I have 4 subroutines called “u”, “x”, “t”, “a” and MOVI sword (4) has the letters “u”, “x”, “t”, “a”
Sub u
;--------
sub x
;--------
sub t
;--------
sub a
;--------

but it gives the following error
Error: Expected Label

Gosub does not accept a variable?
if no, what I can do?

please help me

Gosub requires a label to jump to - it won’t take an array as an argument.

Check out the Atom Pro manual on for the exact syntax, I know the Atom will also take value arguments, but not in the way you’re hoping. Its actually a very interesting thought, though, and entirely possible to do in C with function pointers.

In this case, you’d have to unroll the loop

main
  index2=3
  gosub u
  nap index2
  gosub x
  nap index2  
  gosub t
  nap index2
  gosub a
  nap index2

Perhaps use the “BRANCH” command?

I dont remember the exact syntax, but this seems shorter and better:

main 
  FOR index = 0 to 3 
      BRANCH index 
  NEXT

GOTO main

Yeah, that’s it! That’s what I couldn’t remember… lol

Branch is more like a goto than a gosub, isn’t it? Control wouldn’t go back to the loop without another label and goto.

MAIN 
  FOR index = 0 to 3
    BRANCH index 
    RETURNTOLOOP
    nap index2
  NEXT

U
  ' Do stuff
  GOTO RETURNTOLOOP

Here is a trick for using branch to handle subroutines.

[code]i var byte

main
for i = 0 to 3
gosub branchsub
next
goto main

branchsub
branch i,
return ;need this return just incase i is ever larger then 3

U
;do stuff
return ;returns to next line after gosub branchsub

X
;do stuff
return ;returns to next line after gosub branchsub

T
;do stuff
return ;returns to next line after gosub branchsub

A
;do stuff
return ;returns to next line after gosub branchsub[/code]

Ah ha!

That’s the perfect solution, make the BRANCH routine part of a sub routine!

I’m marking this one down in my book of tricks. 8)
