- DOCUMENTATION FOR CPMDEC.FOR
-
- Overview:
- This program allows handling of 8" single density CPM
- format disks on a PDP-11 series computer. The program makes
- use of a menu to allow viewing or printing the directory,
- copying files to or from the CP/M disk, erasing files,
- initializing the disk, etc. In the Binary copy mode, the
- entire file is copied. In the ASCII copy mode, the EOF
- is detected (in either direction) and translated. For the
- user with many files to translate, the program provides
- a loop to copy ALL files from the CP/M disk. In this case,
- a floppy disk in the other drive is used for all output
- files (usually, any device in the system can be the
- target).
-
- Requirements:
- PDP-11 series computer with RX-01 or RX-02 disk drives.
- RT-11 or TSX-Plus operating system (this program has been
- tested under RT-11 V4 and TSX+ V2.2 and V3.01).
- DEC FORTRAN IV V2.5
-
-
- Compatibility:
- This program makes extensive use of RT-11 system calls,
- notably ISPFNW but also LOOKUP, IENTER, and others.
- Accordingly, if you want to modify it to run on another
- system, you are on your own. Good luck!
-
- Notes:
- Due to the extensive use of the USR module (part of the
- RT-11 operating system), the program MUST be compiled
- /NOSWAP (ie, .FORT/NOSWAP/WARN CPMDEC/LIST).
-
- This program occasionally crashes TSX-Plus. My Theory is
- that this problem is related to the USR swapping over the
- program, but I am probably wrong.
-
- For the user who must manually type this program in
- (the problem of distributing a DEC program on a CP/M
- format disk) a short version (CPMD2.FOR) is provided.
- This program, when run, will automatically copy CPMDEC.FOR
- to DK0: (and do nothing else). Then compile CPMDEC.FOR
- and you are ready to go.
-
- If you find any bugs, let me know.
