Re: why doesn't my system('cls') work?

Well, right off the bat, there is no program named cls.com or cls.exe out there. It's a command built into the shell, cmd.exe.

--bibo

UPDATE

My point is this: system and spawn and fork and their tickish brethern will launch a new process. Those new command windows could clean their own screens with cls, but you cannot clear the screen of the currently running command window by starting a new process.

is this helping?

Just for the record, `system 'cls';` does clear the screen on a sane Win(NT\|2K\|XP) installation.	[reply] [d/l]

might want to check that. the following outupt is from win xp `C:\WINDOWS>dir cmd.exe /s Volume in drive C has no label. Volume Serial Number is 3833-835E Directory of C:\WINDOWS\system32 08/23/2001 04:00 AM 375,808 cmd.exe 1 File(s) 375,808 bytes` [download] you may wany to double check your `%PATH%` and make sure the directory that contains your `cmd.exe` is in it. -HTH	[reply] [d/l] [select]

The poster stipulated there was no cls command... not no cmd command.	[reply]

sorry for misreading that, but we did fix OP's `%PATH%` problem.	[reply] [d/l]
