"register"

Peter Moncarey

hello,

If i enter the word 'register' it appears in blue, so that means it is a 'reserved keyword'.I wonder what the purpose is of this keyword 'register' and for what i can use it... Can anybody help me?

(I'm a newbie in Keil C51 compiler.)

thanks and greetz

    "If the reason for using "register" is a time critical function, C should not have been used anyhow."

    What other possible reason could there be?

    Here we are in PC land again. for a PC application you might want something as fast as possible without the programmer making any effort - typical PC programmer attitude.
    For a microprocessor application the above doesn't cut it, in that case it is as fast as possible with the programmer making an effort - which should be the attitude of every microcontroller programmer - and that is impossible in C.

    Please note: I recommend that all non time critical code be written in C, I am not an assembler fanatic; however when I see microcontroller programmers try to avoid the dreadful assembler I cringe.
