How To Pass Parameters

Examples of parsing parameters to byte codes :

1.  Move 8 bit signed value to floating point variable


    opMOVE8_F (SOURCE, DESTINATION)

    Parameters:
        (DATA8) SOURCE              (could be constant or variable number)

    Returns:
        (DATAF) DESTINATINATION     (this must be a variable number that has 4 bytes allocated and is aligned at a 4 byte boundary)






2.  Pass two parameters to a SUBCALL

    Parameters must be aligned so 32 bit variables come first then 16 bit and at last 8 bit variables

    Parameters are placed in the SUBCALLs local variable space so the first parameter will be LV0(0)

    When referring to parameters in a SUBCALL refer to local variables.

    Array handles must be seen as input (or input/output) parameters because it is a handle (number)
    to be copied into the subcalls local parameters.
