6. EMULATOR MACRO $PLAN, INSTRUCTION LIST

The macro $PLAN is the central component of the conversion system - it represents a software model of the ICL 1900/2900 CPU which will ideally produce identical output to the hardware original at any stage of processing. Additionally, it emulates functions of the ICL operating system like file I/O and interaction with the operator console. 

A comprehensive PLAN-ConPLAN instruction list, with a detailed discussion of the emulated instruction set, is available from Austrosoft. Please send your request to to the support email address provided on the Home Page.
