Hex Poker

Hex Poker © 1981 Fabris, Robert.

The Hex Poker program is a small utility routine that will store hexadecimal Z80 Opcodes into memory one byte at a time. The starting address is entered in decimal (such as using 20180, the Bally BASIC line buffer starting location - note that it is 20154 in the AstroVision BASIC - Robert Fabris). This is identified as variable B. As each memory location is listed on the screen by this program, enter a two-digit hex code from the keypad. After the last byte, key in WORDS RETURN. To run the machine code routine, enter CALL B where B was the starting address.
