No. The SHELL line does get executed before the INSTALL lines, but all
it does is tell DOS where to get the command processor. DOS only
actually loads the processor at the very end of CONFIG.SYS, *after*
everything else. If you need proof, just try loading everything you
have in AUTOEXEC.BAT (including SETs) in CONFIG.SYS, and using Windows
as your command processor (SHELL=C:\WINDOWS\WIN.COM). Everything you
specified in the INSTALL lines will get loaded before Windows, and
COMMAND.COM is never required, but PATH etc. are present under
Windows. Try running MEM directly from Win, ie without using a DOS
box; just use File/Run and type MEM.
