# File suffixes:
# .c	C source (often useful both for UNIX host and SAPC)
# .s 	assembly language source
# .opc  relocatable machine code, initialized data, etc., for SA PC
# .lnx  executable image (bits as in memory), for SA PC (Linux a.out format)
# .syms text file of .lnx's symbols and their values (the "symbol table")
# Symbol file "syms"--for most recently built executable in directory

# PC executable--tell ld to start code at 0x1000e0, load special startup
# module, special PC C libraries--
# Code has 0x20 byte header, so use "go 100100" (hopefully easier to
# remember than 100020)
