I have a file. I have a group number within the file. I want to be able to produce a list of record keys within that specific group.
Is there a function or programming method that would allow me to get a list of record keys from a specific file group?
System is Arev 2.10, file is large. Using RBasic is no sweat. Anything that would help would be appreciated.
Thanks in advance!
If it were me, I would get the DOS filename from REVMEDIA and use OSBREAD navigating the linear hash structure to read the data. That is pretty much what DUMP does.
I agree with Victor,
but there may be a faster solution,
calling RTP57 directly using READNEXT code.
Propper FMC (pointer to the group) must be set.
Unfortunately, nobody confirm this is correct.
Probably the FMC has another structure in some occassions.
