 Syntax
 
    fn_shl( <nInt> | <cInt>, <nBits> ) -> nResult
 
 Arguments

   <nInt> may either be a numeric integer, or a 16-bit character string
   that is the binary representation of a numeric integer.

   <nBits> is the number of bits to shift left and must be a numeric.

 Returns

    <nResult>, a numeric

 Description

     The value returned is obtained by shifting the bits in <nInt> to
     the left.  <nBits> determines the number of bits to shift.
     If any parameters are invalid, the function will return zero.
