Shot meself in the foot again...

Number or PORT real name or Alias to pin it has to work

Have a look to section 4.11, or in MCS Help topics>>PICBASIC PRO Basics>>> Pins

To me, real port name (PORTB.3) or aliases (DO) is more valuable than pin #.

But... it's me

    SS                   var PORTB.1 ' ISD4002 SS pin
    SCLK                 var PORTB.2 ' ISD4002 SCLK pin
    MOSI                 var PORTB.3 ' ISD4002 MOSI pin
    MISO                 var PORTB.4 ' ISD4002 MISO pin

    ss = 0
    shiftout MOSI,SCLK,LSBFIRST,[ISDword\16]
    ss = 1
