REM DEPLOY.BAT - One-time deployment script for DOS Update System
REM
REM Purpose: Installs the new NWTOC update system on DOS 6.22 machines
REM Location: Run from T:\COMMON\ProdSW\DEPLOY.BAT
REM
REM What this does:
REM   1. Backs up current AUTOEXEC.BAT
REM   2. Prompts for machine name (TS-4R, TS-7A, etc.)
REM   3. Updates AUTOEXEC.BAT with MACHINE variable
REM   4. Copies update batch files to C:\BAT\
REM   5. Runs initial NWTOC to download all updates
REM
REM Version: 1.0 - DOS 6.22 compatible
