gosub ,link-goto and return: return without gosub.

[davos1]

Hi, I am calling a block with a gosub, then a link is run inside, then a return in order to return to the main block, but that causes an error: return without gosub.

example a: , no link used: works fine.
gosub
print "end"
end

print "in a"
return

example b: a link inside a gosub
this causes the error:
Runtime Error in program 'untitled': return
RETURN without GOSUB

gosub
print "end"
end

print "in a"
link #l,"go to",[g]
wait
[g]
print "in g"
return

Your program encounters a "wait" statement before the "return" statement. You cannot stop program flow inside of a gosub/return block of code, so the parser "sees" the "wait" as the end of the code block.

Once your program hits a wait the program will stop running. You will no longer be in the subroutine.

Try this:
gosub [a]
wait
[a]
print "in a"
link #l,"go to",[g]
return
[g]
print "in g"
return
