If you gosub contverde, you must have a RETURN at the end to come back.

Same with gosub cuelga.

gosub contverde
;------------------------------------------------------------------------------
; Miramos si esta activo el rojo si no lo esta, seguimos mirando
; para asi verificar que está en transito la llamada.

mirarVerde:
if ldgreen=1 and tamper=0 then mirarVerde
if ldgreen=0 and tamper=0 then llama2 ; tengo dudas aqui <=== this means GOTO LLAMA2
ContVerde:
if ldgreen=1 and tamper=0 then CondiCuelga=1 ; aqui esta el problema
if tamper=0 and CondiCuelga=1 then gosub cuelga
RETURN <=== are you sure you don't want a RETURN here?
cuelga:
pause 10
low relcall
;if condicuelga=0 and tamper=0 then goto cuelga
;if ldgreen=1 and tamper=0 then goto inicio
RETURN <=== are you sure you don't want a RETURN here?
end

Very important, if you GOSUB to a subroutine, do not GOTO out of it.

You must stay within the subroutine and exit using RETURN.

There are probably exceptions, but you can quickly get into trouble if you don't keep your logic clean.
