 is possible a variable goto or gosub? maeloterkim Junior Member Posts: 47 Threads: 22 Joined: Mar 2019 Reputation: 0 09-27-2021, 01:50 PM (This post was last modified: 09-27-2021, 02:03 PM by maeloterkim.) Hi in the original  ZX spectrum basic you can do this goto MyVariable  or gosub MyVariable  where this variable must be a line number this way we can goto or gosub to diferents routines that are in diferents line numbers but i tried this example with the compiler and says error: Syntax Error. Unexpected token 'MyRoutines' This is the example you can try: dim MyRoutines(2) as uInteger => {  @MyRoutine1, _    '' address of my routine 1                                                        @MyRoutine2, _    '' address of my routine 2                                                       @MyRoutine3 _    '' address of my routine 3                                                   }                                 dim myVariable as uByte = 1 gosub MyRoutines(myVariable)     '' you can try goto too myLoop: goto myLoop MyRoutine1: print "MyRoutine 1" return                    MyRoutine2: print "MyRoutine 2" return                    MyRoutine3: print "MyRoutine 3" return        Is possible do something like that without a lot of ifs ? I think i found a solution The solution i found is this: dim MyRoutines(2) as uInteger => { @MyRoutine1, _ '' address of my routine 1 @MyRoutine2, _ '' address of my routine 2 @MyRoutine3 _ '' address of my routine 3 } dim myVariable as uByte = 0 poke uInteger (@pokeGosub1 + 1), MyRoutines(myVariable) pokeGosub1: gosub MyRoutine1 myLoop: goto myLoop MyRoutine1: print "MyRoutine 1" return MyRoutine2: print "MyRoutine 2" return MyRoutine3: print "MyRoutine 3" return I do a poke with the routine direction just before the gosub maybe you can implement this with the compiler this way the behaviour is more like the original ZX spectrum « Next Oldest | Next Newest »
