2.1.2.2.1 Record Processing for UNIX Files
I read:
Each record prefix is mapped by the IGGRPFX macro. It is the following four
bytes:
Offset Length Symbol Description
0 1 RPFX00 Reserved.
1 3 RPFXLLL Length of record that follows this prefix.
... If any record in the file consists of zero bytes (that is, the length
field in
the record prefix contains zero) or if any record is longer than the length
of the buffer, it results in an error return code for GET.
Sigh. Morons. Why did they do that!? It's like being back in old OS/360
which specified the minimum count field in an RDW as 5.
