Operator Shl= (Shift Left And Assign)

Shifts left and assigns a value to a variable

Syntax
   Declare Operator Shl= ( ByRef lhs As Integer, ByRef rhs As Integer )
   Declare Operator Shl= ( ByRef lhs As UInteger, ByRef rhs As UInteger )
   Declare Operator Shl= ( ByRef lhs As LongInt, ByRef rhs As LongInt )
   Declare Operator Shl= ( ByRef lhs As ULongInt, ByRef rhs As ULongInt )

Usage
   lhs shl= rhs

Parameters
   lhs
      The variable to assign to.
   rhs
      The value to shift lhs left by.

Description
   This operator shifts the bits in its left-hand side (lhs) parameter a 
   number of times specified by its right-hand side (rhs) parameter, and 
   assigns the result to lhs. It is functionally equivalent to:
      lhs = lhs Shl rhs

   This operator can be overloaded for user-defined types as a member 
   Operator using the appropriate syntax.

   Note: Similarly to the operator '=[>]' (assign), the alternative symbol 
   'Shl=>' can be also used.

Example
   Dim i As Integer
   i = &b00000011   '' = 3
   i Shl= 3         '' = i*2^3
   '' Result: 11000          24            24
   Print Bin(i), i, 3*2^3
   Sleep

Dialect Differences

     alias __Shl=.
