Hi,I've just thought of this simple piece of code as an example 100 90 80 70 60 5 @1 case 4 s0 :0 @Test( l0 ) d (>G:Var1) 75 > if{ l0 -- s0 g0 } Now, (G:Var1) will return 80As you can see, "goto" operators are very powerful when you need to extract values from tables.Tom

way over my head tom. i guess i should have prefaced my question "can you explain to an idiot how to use a goto statement" my only exposure to programing is the xml stuff in fs9. except for some basic in collage, before you were born. bit operators ( thinking thats what you wrote) are swahili to me.heres what im trying to do.made a hud controler, i have a on/off switch that is on a side panel. i have a 'c' gauge from doug dawson that lets me monitor the status of the screens defined in the panel config from an xml program. got that working and being a glutton for punishment, now i want to add more hud windows for various brightness settings. i have to qualify is the switch on, am i in the forward screen so i can PANEL_ID_TOGGLE , is the hud screen that matches the brightness switch on/off, then turn the correct hud on/off to match the switch, make sure the other huds are off. with the addition of 3 more hud screens the qualifing is getting nasty to a non programer. with a 'goto' i could knock of multiple steps. i guess im thinking more of a 'goto' like in basic. if xxxx then skip down farther down the gauge to line so&so or some flag. then i will not have to ask the same thing over and over again in every line of code.(L:switchon,bool) if{bla bla}(L:switchon,bool) if{ladeeda}(L:switchon,bool) if{something yet again}what i need(L:switchon,enum) 0 == "SKIP TO brother the darn things off "

ridgell,When I was in college, Fortran was the vedette and PC+Basic just newborns.If you want to use "goto" as a jump to avoid some code execution, try something like:(Code_a) if{ g0 } (Code_:( (blabla)(Code_c) (blabla):0(Code_d)(Code_e)If condition in Code_a is met, program jumps to :0 label;Code_b and Code_c are ignored, and processing continues from Code_d on.Now, in case you want to terminate processing inside the , you may as well replace "goto" for "quit", like:(Code_a) if{ quit } (Code_:( (blabla)(Code_c) (blabla)Here Code_b, Code_c, etc are ignored too.Hope to be clear enough this timeTom
