creating x characters

I'm very new to c and I need help with this one.

I'm editing some legacy code, it talks to a VT100 terminal. We used to use a DEC terminal and it had it's own propritary VT100 commands, one of them being erase X number of characters, now we are using a VT100 emulator and this command does not work.

I came up with this but it didn't work.(compiled fine though)

char tstr[20];
memset(tstr,' ',num); write (num) spaces
memset(tstr,'',num); write (num) backspaces

can anyone think of an easy way to erase X number of characters and return to starting position?
