Hi, why does mspgcc uses
#define NULL 0 ? Why not 0x6000 like on the Honeywell-Bull mainframes or another value like 0xffff or an address where is noting in every msp430? The value 0 makes it a little complicated to use the first 16 bit (where IE1 + (IE2<<8) are) e. g. as an interrupt vector (C-FAQ 5.19). It's not important but because the standard (C99) does say nothing about the value of macros like NULL; it's implementation defined. But there must be a reason why the NULL macro is expended to 0 and i would like to know why ;-) By the way: thanks for the answers to the standards :-) Rolf F.
