Section 11,68: MVBITS

 CALL MVBITS (integer1, start1, len, integer2, start2)
 A subroutine that moves bits from one location to another.  Specify
 the arguments as follows:

    integer1   Is an integer variable or array element that 
               contains the bits to be transferred.

    start1     Is an integer expression that identifies the 
               position of the first bit within "integer1" 
               to be transferred.

    len        Is an integer expression that specifies the 
               number of bits to be transferred.

    integer2   Is an integer variable or array element that 
               identifies the location to which the bits are 
               being transferred.

    start2     Is an integer expression that identifies the 
               starting position within "integer2" for the bits 
               being transferred.

 The low-order bit in either integer is position 0.  The values of
 start1+len must be < 32, and start2+len must be <= 32.
