Referencing Fields from an Externally Described File

I am brand new to RPG programming.

F/SPACE 2                                                      
FVSPerf  IF   E           K Disk    Prefix(s)               
FVhipp  O    E              Printer Prefix(rp) OfLInd(*IN90)

With the code above I am trying to define an external table file and prefix it. However when I try to set any fields from the Vhipp print file, like so:

Z-ADD     0             rpRpTot

I get a compile error stating: the name or indicator is not defined. This happens with all fields from Vhipp.

Am I missing something obvious here? My understanding of RPG is once you define an external files you can make reference to its fields, am I defining the file incorrectly?

Solution

  • Turns out I did not have key fields defined in working storage. Those keyfields are the used to populate Venshipp fields but since they were blank/null the table fields came back as being undefined.
