Not to throw wrenches into the works, BUT, using AHP 3.206, with a CM15, I just tested flag operations.
Flags set from the PC ARE seen by the CM15 in a condition clause.
Flags set from the CM15 ARE seen by AHP.
I realise this is contray to the manual you quoted, but a test showed that they do work fine.
Please Note: I must mention the Required Macro execution delay in front of all macros. (At least for me.) If there is no delay at the start of a macro, I cannot guarantee they will run so when I test I ALWAYS put one in.
If you need better response than a delay would give, TEST it before relying on correct operation.
I'm Learning to not include all the test data, just the results, but if you really need to see how I tested this.......
I've learned that what works and what is SUPPOSED to work are two very seperate things......
(Some work better, some work worse and some just work differently. Seems all I do is test.)
