Hi,

I am one of those old person, who is still working with Green Screen. Now I have a requirement. I am developing a function, and when ever i run this function, i want to generate this function automatically and not using @MODX. Any ideas.

I've tried deleting records from genfile, but no help

Regards
Bharat

If you have the bootstrap file def you can set @FREV to blank on FUNCTDEF.

Then, when you try to run the function it will autogen.

Don't do this with globals though.

As Steve says, ProIV will gen functions where @FREV is empty.

The command ENABLE(&#@SUPP-EXEC) is also sometimes useful. This is the equivalent to running @FGEN with N (e.g. not running the function immediately). It calls the Function (and gens it is @FREV is empty) then returns to @PFUNCT if the gen is successful, or to ? if it is not.

You can cause it to return to a Function other than the calling Function by setting @FUNCT to the name of the Function you want it to go to. That's because the value placed in @PFUNCT is the previous value of @FUNCT - normally that's the name of the previous function as that is its default value - but you can change it. You set @FUNCT before you exit the function that links to the one you want to gen.

If you want to trap Gen errors then set @DFUNCT temporarily to the name of the Function to be called (remember to reset it).

This can be useful if you want to automatically attempt to gen a list of Functions, for example. There's also an enable command that can suppress the GEN message somewhere if you need to do that - sorry I can't remember it at the moment.
