- MCOPY47A.BUG February 21, 1988
- ----------------------------------------------------------------------------
-
- A bug was introduced into mcopy beginning with version 4.7a. It only occurs
- when copying large files while running under an RSX. Specifically, my
- problem occured while running Poor Man's Network under ZCPR3.0, ZRDOS 1.7,
- MENU 4.1, and the file size was 36K. Small files seem to transfer with no
- problems. Poor Man's Network has been eliminated as the source of the
- problem, because the failure will occur even when performing a 'local'
- copy on the same machine. When the RSX is removed, the same 36K file will
- mcopy fine with version 4.7a.
-
- In reviewing the updates from mcopy version 4.6 (which works fine) to version
- 4.7a, 'buffer sizing where an RSX is present' was one of the updates.
-
- The following text is from MCOPY47.FOR:
-
- DateStamper support via DSLIB, use faster CRC3 routines from
- SYSLIB4, more Z80-specific code to trim things down, deleted old
- LDED macro, improved buffer sizing where an RSX is present,
- vastly simplified option processing code, re-ordered user-
- definable options so they could be copied with a block move,
- added $SYS file exclusion option, etc., etc.
