MIPS function to read coordinates

# Local variables for readCoords() function.

strtRowPmt: .asciiz " Enter Start Coordinates ROW: "

strtColPmt: .asciiz " Enter Start Coordinates COL: "

endRowPmt: .asciiz " Enter End Coordinates ROW: "

endColPmt: .asciiz " Enter End Coordinates COL: "

err0: .ascii " Error, invalid coordinate value. "

.asciiz "Please re-enter. "

err1: .ascii " Error, end coordinates must be > then "

.ascii "the start coordinates. "

.asciiz "Please re-enter. "

spc: .asciiz " "

# Prompt for and read start and end coordinates.

# Also, must ensure that:

# each value is between 0 and COORD_MAX

# start coordinates are < end coordinates

# -----

# Arguments:

# startRow, address

# startCol, address

# endRow, address

# endCol, address

# Returns:

# startRow, startCol, endRow, endCol via reference
