/*
 * NAME
 *	syscall1.c -- test syscall
 *
 * CALLS
 *	syscall
 *
 * ALGORITHM
 *	Use syscall to simulate some section 2 calls and make sure
 *	things work as expected.  Pretty simple, but if it works
 *	for a few it should work for all.
 *
 * RESTRICTIONS
 *	The syscall numbers are system dependent!!  They represent
 *	entries in a table and can be changed from kernel to kernel.
 *	They ARE differnet between vax 4.2BSD and our ported system.
