Your "SPRE" can only be one value. It stands for "Special Prefix" and is defined in LD15 (Print= LD21, REQ prt TYPE cdb)
The point to making it a 4 digit number is so it does not suck up an entore "thousands" block of DNs.
If for example your SPRE was 7, then 7000-7999 are unavailable to you for use. Call Pickup in the system would be "73"
If you made the SREE 7999, then you could use 7000-7998 for DNs, and make feature codes that start with * and #.
If the FFC for LD57 PUGR does not work, check the TN of the user for CLS GPUA and also that they have a value other than zero in RNPG.
Here is an old example of my FFC codes. Note each feature can have many activation codes...as many as you can type.
