Hi Russell,

IAR changed things when they created 6.10. Totally incompatible with their earlier 8051 compiler...

Bit variables are now "bool" instead (probably to match their other compilers). So instead of:

bit test1;

you would use:

bool test1;


Regarding interrupt service routine declarations, from the manual:

The #pragma vector directive specifies the vector of an interrupt function whose declaration follows the pragma directive.

Example:

#pragma vector=0x14
__interrupt void my_handler(void);

I've had 6.10 for several months now, but haven't really used it, I'm still waiting for their upgrade and documentation that supposedly will allow existing users to migrate to the new compiler.

So far from my impressions of it, if you've got the money to buy this compiler, check out Keil!
