Transferred form values

I think values are transferred using Key Values in the .scr file. For instance in HR11, the .scr has an entry that looks like this:

2 EMP-EMPLOYEE N 09 SL H07

Any screen that has a field with the key number H07 will get passed the value when form transferred.

And how would I retrive these values? Thanks

You would treat it like any other screen field:

for example to check if the employee filed is populated, in the PD

(IF GM11F3-EMP-EMPLOYEE NOT = ZEROES)

Sorry for being so stupid here, but how would I assign the EMPLOYEE value to a variable within Design Studio. I'm not in the procedure division.

Opps. Did not realize this was Design Studio forum.
I was thinking in 4GL terms.

var sEmployee = lawForm.getDataValue("EMP-EMPLOYEE");
