You cannot declare SUBs before the INTERRUPT command.
Do this:

 


[code]
' -------------------------------------------------------------------------
INTERRUPT 50_000 

  GOTO ISR_Start
' ------------------------------------------------------------------------- 


  

' -------------------------------------------------------------------------
' Subroutine Declarations

CHECK_SPINNING  SUB     0                       ' 
MEM_OUT         SUB     3                       ' write value to memory
MEM_IN          SUB     2                       ' read byte from memory

' ------------------------------------------------------------------------- 


ISR_Start:

[/code]
You have some problems in your code though. For example from within the interrupt routine you are using "GOTO Check_Spinning", but that is a subroutine. If you really just want to call the Check_Spinning subroutine, just use "Check_Spinning" without the goto.
