you typed them. For example: Print "ZERO PAGE RAM":M0,FF:Print"END OF ZERO PAGE" REMEMBER: ALL PROMOS 2.0 COMMAND PARAMETERS ARE ENTERED AS HEXADECIMAL NUMBERS. ERRORS If you make a mistake typing in a PROMOS command, chances are you'll be advised by the SYNTAX error message. If you fail to supply all the parameters required by a command, an UNDEFINED FUNCTION error will result. If you input incorrect hexadecimal numbers, an ILLEGAL QUANTITY error will be reported. Some PROMOS commands report other errors as may be necessary. PROMOS 2.0 COMMANDS THE G COMMAND- Print command Glossary. This isn't really a command at all. Type a G and a carriage return and a list of the PROMOS commands and an example of each is printed on the screen. If you commit only one command to memory, make it this one. THE R (or {}) COMMAND- Read EPROM data into computer memory. By reading an EPROM, we mean transferring some or all of the information it contains into the computer's memory. The key letter can either be R or {}, the English monetary symbol. Example: R2000, 3FFF, 0, 6 The meaning of this command is: fill computer RAM from 2000 to 3FFF with data from this EPROM, beginning at EPROM address 0000. The '6' is a parameter called the CONTROL WORD. It is a number that tells the PROMENADE everything it needs to know about the particular EPROM you are dealing with. In the example, 6 is appropriate for the 2764A. A list of control words appears inside the back cover of this manual. A detailed discussion of control words and what they mean is presented in APPENDIX A. Another example: {} 5000 BFFF 1000 E6 Here, we have used the {} symbol rather than R. The command does exactly the same thing either way. In this -7-
