only if the relevant dialog is a "master dialog".

Description:

Return value:

IF REG[15].VLD == FALSE

REG[15] = 84

RETURN

The RETURN function can be used to prematurely terminate execution of the current

subprogram and to return to the branch point of the last CALL command.

If no RETURN command is configured in the subprogram, the subprogram will run to the end

before returning to the branch point.
