errorlevel

[edit]

How do I view the current errorlevel in MS-DOS 6.22?

ECHO %ERRORLEVEL% doesn't seem to work.  Preceding unsigned comment added by 110.77.173.30 (talk) 07:55, 17 November 2017 (UTC)reply

According to this page, you have to use conditional statements or loops to determine the error level in MS-DOS.Best Dog Ever (talk) 08:20, 17 November 2017 (UTC)reply
Only works in scripting due DOS prompts overwrites the ERRORLEVEL. So use in BATch files only. --Hans Haase (有问题吗) 09:56, 17 November 2017 (UTC)reply
Try this (it is the program startup line in a .BAT file):
yourprogram.exe -v %1
