Hi,
I have a fairly simple question.
I have a 'power on' macro that powers up all my stuff in one go (projector, amp, lights etc).
The problem is if somebody hits the 'power on' button when everything is on already which would actually turn things off.
What I need to do is set a global variable at the start of the macro..ie POWER=ON
...question is, how do I then check to see if POWER=ON or POWER=OFF and quit out of the macro displaying a message box if the POWER=ON or let it continue if POWER=OFF??
many thanks
Phil

If you had a global variable called POWER, you could use this to check it...
if( {POWER}="ON", 999, 1)
If you did a... Set Global | {POWER} | "ON"
This would jump out of the macro when the variable is "ON", and, just drop down to the next line when not.
But, what you have is a feature, not a bug! That same macro can turn off everything, too!

Thanks Tony,
I have tried that, but the Macro still plays regardless of the value of the variable.
The Macro is:
if("{POWER}"="ON", 999, 1)
ph_setglobal_a( "POWER", "ON" )
--- rest of the macro below ---
Thanks
Phil

Hmm. That makes no sense. Something else is going on, because what you posted works here.

Very odd. Maybe the clue is in the rest of the macro. It's only a test macro with one extra line which is turning on an amp via IR

Phil,
The only thing that I can think of is to make sure that the if("{POWER}"="ON", 999, 1) is the formula for a macro "Jump" command.
If you can, export the macro and paste the SQL here and we'll get it working for you.
Dave.

Hi Dave,
macro is:
insert into macroheader values ('TEST','TEST',0,0,1);
insert into macrodetail values ('TEST',1,38,'',0,'if( "{POWER}"="ON", 999, 1) ',0);
insert into macrodetail values ('TEST',2,38,'',0,'ph_setglobal_a( "POWER", "ON" )',0);
insert into macrodetail values ('TEST',3,0,'SWITCHER',4,'',0);
Many thanks
Phil

Ah ha!
The second line of the macro should ba a Jump (16), not a Formula (38).
