BITRL 

The BITRL function returns the value of a particular bit of an
expression, where 15 is the Most Significant (or leftmost) bit.  The
result is a SHORT INTEGER.

Syntax 

BITRL(N1,N2)

Parameters 

N1               Binary representation of a numeric expression.  This is
                 a SHORT INTEGER. This is the number containing the bit
                 to be extracted.

N2               Binary representation of a numeric expression.  This is
                 a SHORT INTEGER. This is the number of the bit to be
                 extracted from N1.

Examples 

The example below shows the bit layout for N1.  It shows the result of
the BITRL functions for several values of the second parameter (N2).

     Bit Number:  15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0
     N1=           0  1  1  0  0  1  0  1  0  0  0  1  1  1  0  1

     BITRL(N1,15)=0, BITRL(N1,11)=0, BITRL(N1,8)=1, BITRL(N1,3)=1
