int e l CHAPTER 3 Description of EPROM File Commands DESCRIPTION OF EPROM FILE COMMANDS One of the unique and powerful features of MCS BASIC-52 is that it has the ability to execute and SAVE programs in an EPROM. MCS BASIC-52 actually generates all of the timing signals needed to program most EPROM devices. Saving programs in EPROMS is a much more attractive and RELIABLE alternative relative to cassette tape, especially in control and/or noisy environments. The hardware needed to permit MCS BASIC-52 to program an EPROM device is minimal, typically only one NAND gate, three or four transistors, and a few resistors are all that is required.
Details of the hardware requirements are in the EPROM PROGRAMMING section of this manual. MCS BASIC-52 can save more than one program in an EPROM. In fact, it can save as many programs as the size of the EPROM memory permits. The programs are stored sequentially in the EPROM and any program can be retrieved and executed. This sequential storing of programs is referred to as the EPROM FILE. The following commands permit the user to generate and manipulate the EPROM FILE. - 20 -
