Summary: Turbo Pascal bios bypass



    Do any of you bright Turbo users out there know of the
    ramifications of turning on or off the following 
    parameters (under MS-DOS):

    $V  - paramter type checking
    $K  - stack checking
    $R  - array index range checks?

    Yes, I've read the descriptions in the reference manual,
1.  what I'm asking is -> What CODE ramifications are there?

    I know CTRL-C checking significantly reduces speed due to
    int 3 checks.  What happens with the above?

2.  Also, what are the switches for "fast" or bios usage?
    I recall something like the $G or $P swithes?  Any help?

3.  Is calling a routine with PROCEDURE(variable-name: STRING50);
    better or worse (stack wise) than PROCEDURE(var: variable-name: STRING50);
    STRING50 defined as type STRING50: array[0..49] of char;
   

Thanx for any help!

Mike
