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.
