Create a structure called GSstring and put the length word in the length.

struct  GSstring {
        int     length;
        char    string[255]; /* or whatever buffer size you need */
};

Use Orca/C's strpos( string, "/0") to return the length and plunk that into
the length element and use strcpy (string1, string2) to copy the string into
the structure. (This is off the top of my head,so I do not have the correct
syntax to copy to a structure with strcpy. I leave this as an excersize for
the class to complete at home. :)

Orca/C has a function called c2pstr that converts a C string to a Pascal
string, but the length is only 1 byte long, GSOS requires 2 bytes.

Perhaps when you have it working you could post it here under the name
"c2GSstr".
