Question !

Hi a am writing a C Programe on Vi Editor (File Handelling),and i am compiling it using fcc but it not compiling ,Even Vi not saving my file.Tell me how can i do that.One More Thing I want to know that ,Is their any subsitute of conio.h.

Have you checked your system space?
just try
bdf .

Have you included stdio.h ?
then try

cc -o aa aa.c

Check your /var/tmp. The VI command uses /var/tmp (linked to tmp when you have /tmp mounted).

Check your space in the /tmp directory.

While I am thinking of it here are some Other cool VI tips!!

Just for clarification. If you were in Single User Mode. You would not have access to /tmp. You could mount /var and that would give you access to /var/tmp which would then allow you to vi a file in single user mode. You may also have to mount /usr as well.

You might want to check the permission on the directory and the file you are trying to run.
