I have this assignment due in about 7 hours.
I desperately need help, if anybody can help please do so.
This involves OpenGL

I need this two functions finished
| Code: | ; ******************************************************************
; Function getParams()
; Get, check, convert, verify range, and return the
; A value, B value, draw color, and draw speed.
; Example HLL call:
; stat = getParams(argc, argv, &aValue, &bValue,
; &drawSpeed, &drawColor)
; This routine performs all error checking, conversion of ASCII/Vegismal
; to integer, verifies legal range of each value.
; For errors, applicable message is displayed and FALSE is returned.
; For good data, all values are returned via addresses with TRUE returned.
; Command line format (fixed order):
; -a <vegismalNumber> -b <vegismalNumber> -ds <vegismalNumber>
; dc <vegismalNumber>
; -----
; Arguments:
; 1) ARGC, value
; 2) ARGV, address
; 3) a value (dowrd), address
; 4) b value (dword), address
; 5) draw color (dword), address
; 6) draw speed (dword), address
