[net.micro.cpm] possible bug in CP/M 3.0 \"PIP\"

prindle@nadc.ARPA (08/18/86)

CP/M 3.0 supports the character "_" (underline) as valid within a filename and
it is so documented.  Builtins such as ERASE and RENAME have no trouble
handling this, nor does either the builtin or transient DIR.  However, PIP just
gets bent out of shape and refuses to accept the syntax (e.g. a:=b:tvx_io.c).
I am referring specifically to the Commodore 128 version of 3.0, but suspect it
is really a generic problem.  Digital Research sent me their set of application
notes, but I didn't see this mentioned as a fixed bug.  I don't suppose there is
any easy fix short of re-writing PIP?

Sincerely,
