Maintain Common Variables

Common Variables provide an alternative method of accessing and storing values in the PROIV’s Common Block. They offer an alternative to the @$COM1..10 and @#COM1…10 system variables and are system-wide variables that facilitate transfer of data from one function to another. Once defined, values can be written to or retrieved from the Common Block through use of four Global Logics: @PUTVAL, @GETVAL, @PUTNVAL, and @GETNVAL. The developer creates a new variable in a Screen function and uses @PUTVAL and @GETVAL logics to pass values between non-Global Logics, or those that are not linked together with Interface Maps.
