   * @brief Emit ASM implementation for <b>COLORMAP AT [int]</b> instruction

   * This function allows you to set the starting address, in memory, for the 
   * colormap and it is the version that is used when the memory is given as a
   * direct number (i.e.: $8400). The input parameter is decoded and declined 
   * according to the hardware limits. So it is not said that exactly the 
   * given address is set.
   * 
   * On some machine calling this instruction will define the special variable:
   * 
   *  * `COLORMAPADDRESS` (VT_ADDRESS) - the starting address of colormap memory
   * 
   * @param _environment Current calling environment
   * @param _address Address to use
