Hi Bob



 BL> This came out of a tight loop (zmodem?) where I was calling a

 BL> function in Pascal several times and Paul was using a macro...

 BL> The Pascal approach ran at HALF speed. When I changed my

 BL> function to code written several times as you suggest, it was

 BL> as fast as C and five-times as messy. Calling the function was

 BL> taking most of the time.



 RM> Declare the function "inline". Neat, fast, takes a bit more

 RM> space in the exe.



 BL>   In C, or Pascal?



C. I don't do Pascal.



 BL>   Isn't that what a macro does in C anyway?



yes, but the compiler can give more meaningful error messages



 BL>   I can't see much point in using the inline directive in Pascal,

 BL> unless it is doing the code wrong or you have a specific instruction

 BL> you want inserted right there. Mostly, the Pascal compiler writes what

 BL> I would have written inline anyway.



er.. does inline mean the same in Pascal as it does in C? In C, it

means that when you write a function call, like



  z = add_numbers(x,y);



then instead of placing a call to the function add_numbers() at

that point, the compiler writes a complete copy of the code for

add_numbers, eliminating the function call.



Cheers
