I'm having difficulty accessing a value from an array. Here's an example of what the code is doing:
unsigned char xdata In_Buf[2][70]; unsigned char port;
void main(void){ port = In_Buf[0][0]; . . }
maybe not strange. There are specific C rules about what happens when There are locals and globals with the same name. Lookup "Variable Scope"
"There are specific C rules about what happens when There are locals and globals with the same name." It's not just 'C' - most block-structured high-level languages (HLL) have similar rules. It's a bit like the way you can have many fies on your hard drive all with the same name - you distinguish between them by knowing which folder (directory) each one is in...
just a will goess if 'port' is a rename of SBUF, what you see ios correct Erik
