pib_pchcmd (PCHAR)
This is the address of the ASCIIZ argument strings passed to the program. This string represents command parameters.
The convention used by CMD.EXE is that the first of these strings is the program name (as entered from the command prompt or found in a batch file), and the second string consists of the parameters for the program. The second ASCIIZ string is followed by an additional byte of zeros. A value of zero for the address of pib_pchcmd means that no arguments are to be passed to the program.
