Overriding of Transfer Parameters Using Preprocessing

PPA Preprocessing allows you to override file transfer parameters.

In order to override transfer parameter, you must follow these steps:

1. Only PPA CALLPGM allows you to override the transfer parameters.
2. Use the special token %QUEUE. This token recommends the use of special linkage when communicating to the PPA program. When the %QUEUE token is used, all other tokens and any parameter data is ignored.
3. SAMPLIB program FUSPRE defines how to code a preprocessing program that overrides transfer parameters. Any program name can be used.
4. Add the Preprocessing load module to the Platform Server STC STEPLIB.
5. When the return code is set to 1, transfer parameters can be overridden and the return code will be reset to 0.

The following transfer parameters can be overridden:

• Local File Name
• Remote File Name
• Process Name
• User Data
• Compression
• Encryption

SAMPLIB Member FUSPRE shows how the Preprocessing program can be coded to override transfer parameters. Here is an example of the PPA parameter that allows you to change transfer parameters:

PPA="P,L,CALLPGM,FUSPRE01 %QUEUE"
