13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED

NRCP49 was written in BASIC for operating under TRSDOS2.0. It will also run under TRSDOS 4.X. The BASIC is consistent with Microsoft 1.2 but may be implemented under any similar BASIC language. The Model4 version  was implemented under TRSDOS 6.1.2.
