Documentation: SYSLIB 2.4 Changes (from SYSLIB 2.1)
Location of Doc: SYSLIB User and Reference Manual for SYSLIB 2.4
by Richard Conn, 4 Feb 1983

4.0 Files Affected by this Upgrade
The following files are provided with this upgrade:
Filename.Typ Size K Filename.Typ Size K Filename.Typ Size K
-------- --- ------ -------- --- ------ -------- --- ------
DU2 .ASM 72 LDIRZ .COM 6 SSORT .MAC 14
ZCPR2 .ASM 56 MKDIR .COM 8 SVERSION.MAC 1
DU2 .COM 10 ZCPRHDR .LIB 15 SYSLIB .REL 14
9 Files Occupying 196K, 9 Files on Disk and 45K Free
These files have the following CRC values:
1 File: DU2 .ASM -- Size: 72K -- CRC: 5F 2C
2 File: DU2 .COM -- Size: 10K -- CRC: E7 32
3 File: LDIRZ .COM -- Size: 6K -- CRC: B2 25
4 File: MKDIR .COM -- Size: 8K -- CRC: C2 7F
5 File: SSORT .MAC -- Size: 14K -- CRC: E3 32
6 File: SVERSION.MAC -- Size: 1K -- CRC: 2D 3E
7 File: SYSLIB .REL -- Size: 14K -- CRC: D4 8D
8 File: ZCPR2 .ASM -- Size: 56K -- CRC: 5B F1
9 File: ZCPRHDR .LIB -- Size: 15K -- CRC: 3C 5B
5.0 Reasons for Changes to Programs and Files
ZCPR2 Change Summary:
Mod 0.1 corrected a bug in single-character input
associated with the ERA and REN functions
Mod 0.2 corrected a reliability problem with the ^S
(output pause) function which showed itself
when the TYPE command executed without paging
Mod 0.3 enhanced responsiveness of ZCPR2 in the rare
case where a file which was not $$$.SUB in
the directory A$ contained a "$" character
in its name; in this rare case, unnecessary
disk thrashing occurred, but ZCPR2 continued
to perform correctly
Files Affected: ZCPR2.ASM, ZCPRHDR.LIB
ZCPR2 Utility Change Summary:
DU2 contained a bug in that the queue status report
was calling the wrong numeric output routine
LDIRZ was upgraded via assembly when an error in the
M80 assembler caused a bug to be introduced
in the SSORT Module of SYSLIB 2.4; no change
to the source of LDIRZ was required
MKDIR was affected by the same bug in the SSORT Module
of SYSLIB 2.4
Files Affected: DU2.ASM, DU2.COM, LDIRZ.COM, MKDIR.COM
SYSLIB Change Summary:
SSORT did not define the storage area required by the
identifier "I" and the M80 assembler did not
flag this as an error; instead M80 assigned
the value 8 to the symbol "I", causing memory
locations 8 and 9 to be modified by SSORT;
the error was corrected by changing the name
of the symbol "I" to "IDX" and assigning
storage to this symbol
SVERSION was upgraded to reflect the new version number
SYSLIB.REL is Version 2.5 of SYSLIB
Files Affected: SSORT.MAC, SVERSION.MAC, SYSLIB.REL
