Library Design, f0dder's nightmare.

One of the important piece of criteria for a library module is that it
must work properly, IE, do the thing that such a module is expected to
do and among the thing that are normally expected with a command line
parser is that it can delimit not only on spaces but tabs as well.

For someone who has elected themselves as the critic of other peoples
library design, here is the alternative for any who are mislead by
nonsense of this type.

Here is the input and output from the command line parser that is the
leading edge of f0dder.lib.

H:\ASM2\ARCHIVE\F0DDERCL>main 1 2 3 4 5 6
Arg 0 == <MAIN>
Arg 1 == <1 2 3 4 5 6>

You will note here that the arguments delimited by tabs are all bunched
together as one argument.

Here is how its done using GetCL.

H:\asm2\archive\f0ddercl\stcl>stcl 1 2 3 4 5
6 7 8
1
2
3
4
5
6
7
8

The distinction is about this simple, f0dder.lib as demonstarted with
MAIN.EXE does not properly delimit on tabs where masm32.lib using GetCL
does.

Here is how simple the code is to do it.

cmp len(rv(GetCommandLine)), 128
jbe next
print "Command Line Exceeds 128 Bytes",13,10
ret

next:
invoke GetCL,argnm,clbuf ; get the argument
cmp eax, 1 ; test for valid argument
jne bye ; exit if not
print clbuf,13,10 ; display it at the console
add argnm, 1 ; increment the argument
jmp next

bye:
ret

main endp
