Command-line switches

All command line switches begin with the dash (-) character. If a switch requires an input

value, you can enter it as a space-delimited argument immediately following the switch.

Alternatively, you can attach the value to the switch name with the equals (=) character. For

example, both of these are valid:

-o outfile

-o=outfile

When the value is optional the argument must use the '=' notation (i.e. -switch=val and

not -switch val). Each switch name determines whether the following command-line

word will serve as its argument, will be the next switch, or is an input file. For example, the

following command line causes the assembler to assemble file.s into an S-record file

named new_name.srec:

etpu_bins --asm -o new_name.srec -srx file.s

The assembler processes its arguments from left to right. For example, the following

command line defines the symbol one, reads the input file pre_inc.s, defines the

preprocessor macro TWO, then assembles main.s:

etpu_bins --asm -d one -i pre_inc.s -D TWO main.s

Note:

In the example above, the file pre_inc.s cannot use the preprocessor macro TWO, since

the macro is only defined after the assembler processes pre_inc.s.

Table 4 describes each of the command-line switches the assembler supports.
