bug in XP cmd shell

in the cmd shell help (from cmd shell do set /?), it gives the example

set VAR=before
if "%VAR%" == "before" (
set VAR=after
if "%VAR%" == "after" @echo If you see this, it worked
)

the "if you see this, it worked" never shows.
I am using XP Pro SP3 32-bit on an HT processor that thinks it's a
dual-core.

oops. that example should be

set VAR=before
if "%VAR%" == "before" (
set VAR=after
if "!VAR!" == "after" @echo If you see this, it worked
)

the ! causes delayed expansion at execution.

apparently delayed expansion is not enabled by default...

Jim,
Did you enable delayed environment variable expansion via
CMD /vn
