The variables defined include +.B prefix_start +.B prefix_size +and +.B prefix_data +to define and contain the code, plus integers containing the values of all +exported labels. +Either or both the +.B prog.s +and +.B prog.v +arguments can be '-' for standard in/out. + +.\" The 'src' file can be '-' for stdin but ONLY on 'big' machines. + +.SH OPTIONS + +.\"defaults (off or none except for these; no output is produced without a flag): +.\"-03 native +.\"list stdout (beware of clobbering next arg) +.\"name basename of the source name + +.TP +.B -0 +start with 16-bit code segment +.TP +.B -3 +start with 32-bit code segment +.TP +.B -a +enable partial compatibility with Minix asld +.TP +.B -g +only put global symbols in object or symbol file +.TP +.B -j +force all jumps to be long, don't use this with hand written assembler +use the +.B br\ bmi\ bcc +style opcodes or the +.B jmp\ near +style.
