Re: Using a display file in a batch environment

["Bruno ADIN" <badin@xxxxxxx>]

Bill,

My suggestion to solve your problem would be to use an interesting but not
wellknown feature of RPG : SPECIAL Files.
This feature allows you to attach a user written program to a File
specification. RPG will, then, call automatically the user written program
each time an I/O operation is executed on the file.

2 steps are necessary :

1) Change the source of your interactive program to replace the WORKSTN
specification by a SPECIAL specification. Some small additionnal changes are
also necessary to adapt the program because of limitations of SPECIAL files
(for example EXFMT are not supported and must be split in WRITE + READ
operations codes). All the changes can be done automatically by a tool in
order to create automatically the batch version of your program from the
source of the interactive program (its better to not have to maintain 2
sources)

2) Write the user written program to provide the input that was entered
interactively from ........ whatever you want.

Hope this helps.

Let me know if you want additional information.

Regards.
