C problem.. (Error)

[DarkSun]

hey, I use borland 5.5 dos compiler.
and I got in my learning to the command delay(); in the libery Dos.h
dont know why but when I use this command..
I get a strange error that I never seen befor...

Error: unresolved external '_delay' referenced from c:\L.OBJ

and after I compile and get the strange error... the .exe file disapper ..
no clue what to do.
thanks for the helpers.

The .exe file didn't dissapear. It just didn't compile correctly so it didn't make an .exe file. You might not be using the function correctly. That's all I can pick out. I never used dos.h or delay. I would use the system pause function.

system ("pause");

got it fix.
windows changing the command delay(); to sleep(); .
