Choice.exe is a standard command in Windows 2003, Vista and Windows 7 (for XP you can use the early resource kit versions).
Early versions of Choice.com (not Choice.exe) burn a lot of CPU’s when in a wait state, plus there are some issues where multiple concurrent invocations will clobber each other.
The order of the IF statements above matters, IF errorlevel 1 will return TRUE for an errorlevel of 2
CHOICE can be used to set a specific %errorlevel%
for example to set the %errorlevel% to 6 :
ECHO 6| CHOICE /C 123456 /N >NUL
â€œIf you limit your choices only to what seems possible or reasonable, you disconnect yourself from what you truly want, and all that is left is compromiseâ€ – Robert Fritz
