Yep.

I don't think they were ever public in the true sense and they were removed
from
the system early on (V2R?M?). I didn't realise they had been reinstated.

Obviously because Rochester don't want anyone to know about them unless they
have a need to know. There are a few interesting things one can do with these
programs. Still, I doubt much harm will come from documenting them since I got
the information from a public article by Bruce Lesnick many moons ago. A Web
search may turn up the original source. (Besides, they are not much use without
a good understanding of the program template.)
QSCMATPG
1 Program name Input CHAR(10)
2 Library name Input CHAR(10)
3 File name Input CHAR(10)
4 File library Input CHAR(10)
5 Member name Input CHAR(10)
6 Member option Input CHAR(8)
The Materialize Program (QSCMATPG) API retrieves the program template for an
OPM
program and places it in the specified file member.
Program name: The name of the program to materalize.
Library name: The name of the library containing the program. Special values
are
not supported.
File name: The name of the output file. This is a physical file with a
record length of 80 bytes. The file must exist before the API is called.
File library: The name of the library containing the output file.
Member name: The name of the member to receive the program template. Special
values are not supported.
Member option: *ADD or *REPLACE
QSCCRTPG
1 Program name Input CHAR(10)
2 Library name Input CHAR(10)
3 File name Input CHAR(10)
4 File library Input CHAR(10)
5 Member name Input CHAR(10)
The Create Program (QSCCRTPG) API creates a program from the program template
retrieved by the Materialise Program (QSCMATPG) API.
Program name: The name of the program to create.
Library name: The name of the library to contain the program. Special values
are
not supported.
File name: The name of the file containing the program template. This is a
physical file with a record length of 80 bytes. The file must exist before the
API is called.
File library: The name of the library containing the file.
Member name: The name of the member containing the program template. Special
values are not supported.
Regards,
Simon Coulter.
