tgoto(cm, destcol, destline)
These functions extract and use capabilities from the terminal capability data
extracts the entry for terminal

1024 and must be retained through all subsequent calls
returns \-1 if it cannot open the
file, 0 if the terminal name given does not have an entry,
It will look in the environment for a TERMCAP variable.
If found, and the value does not begin with a slash,
is the same as the environment string TERM,
the TERMCAP string is used instead of reading the termcap file.
If it does begin with a slash, the string is used as a path name rather than
