- DOC FOR MDMLNK v1.00 as of 03-26-84
-
- MDMLNK is a utility for MDM7xx. It allows linking in the assembled
- overlay file without the use of DDT. This may be a bit more foolproof
- than the usuall DDT method.
-
- MDMLNK is self-prompting and will ignore all command line parameters.
- Upon entry, MDMLNK will ask for the INPUT file name. Enter the name of
- the uninstalled MDM7xx.COM file and be sure to specify the full file
- name. Next, you are asked for the HEX file name. Enter the full name
- of the assembled overlay file and be sure to include the .HEX suffix.
- Last, you will be asked for the OUTPUT filename. Enter the name of
- the installed MDM7xx file. Again, be sure to specify the full file name.
-
- MDMLNK will now first read the INPUT file, overlay it with the hex file,
- then write a temporary file which is finally renamed to the output file
- name. The temporary file is used so that the input file can be the same
- as the output file, yet a disk error will not wipe out the original.
-
- Errors will be reported for full directory, unable to write (disk full),
- file not found, and in case the hex file is corrupt. All errors will
- abort to CP/M, possibly leaving a file MDMLNK.$$$.
-
- MDMLNK not only works on any MDM7 file of any size (within reason), but
- it can also (BONUS!!!) be used with XMODEM or any other file which
- will be overlaid by a HEX file which does not change its size.
