int s_end(address)
char *address; /* address of SURVO 84C pointers as a string */
The s_end function copies the SURVO 84C system parameters which have been altered in current module back to the main module. s_end should be called once before returning to the main program in those modules which change any of the scalar parameters r, r1, c, c1, etu, etu1, etu2, etu3, tutpos, erun, edisp. For example, edisp may be changed from its default value 1 to to avoid redisplay of the entire screen after return. Normally s_end is not needed at all.
s_end(argv[1]);
