Major DOS 6.22 compatibility fixes for the Dataforth update system:
Changes Made:
- Replace COPY /Y with XCOPY /Y (COPY doesn't support /Y in DOS 6.22)
- Remove all trailing backslashes from XCOPY destinations (causes "Too many parameters")
- Remove %%~dpnF and %~nx1 syntax (Windows NT only, not DOS 6.22)
- Remove \NUL directory existence checks (unreliable in DOS 6.22)
- Simplify all batch files to minimal, reliable DOS 6.22 patterns
- Use MD >NUL 2>NUL for directory creation (ignore errors)
Files Updated:
- NWTOC.BAT v2.7: Simplified download with XCOPY /Y
- CTONW.BAT v2.4: Simplified upload with XCOPY /Y
- DEPLOY.BAT v2.2: Simplified deployment with XCOPY /Y
- CHECKUPD.BAT v1.3: Removed %~nx1 syntax
- UPDATE-ROOT.BAT: Root redirect script
- UPDATE-PRODSW.BAT v2.3: Backup utility (new file, was UPDATE.BAT in ProdSW)
Why:
- Previous versions caused infinite loops due to COPY /Y not existing in DOS 6.22
- Trailing backslashes on XCOPY destinations caused "Too many parameters" errors
- Complex variable syntax like %%~dpnF is NT-only and breaks on DOS 6.22
- Simplified scripts are more reliable and easier to debug
Testing:
- Deployed to AD2 (192.168.0.6) and D2TESTNAS (192.168.0.9)
- Ready for testing on TS-4R and TS-3R DOS machines
