A program-to-system field is used to communicate between an application
program and the sending system (which is local to the application
program). It is not sent as part of the data record across the line to
the receiving system.
The following rules apply to program-to-system fields:
- The field must be a named, numeric, or alphanumeric output-only
field.
- In the record format, the program-to-system fields must be defined after
all the data fields (those with a use of B or blank).
- A field cannot be defined as both a data field and a program-to-system
field; the field names must be unique.
- A program-to-system field can be named on an EVOKE, SECURITY, TIMER, or
VARLEN keyword.
- The only valid keywords for a program-to-system field are ALIAS, FLTPCN,
REFFLD and TEXT.
