With the cold winter nights now upon us what could be nicer than warming your hands over a hot computer. Sembler, will give you that opportunity with its combination of assembler and disassembler. On running the program a prompt will be displayed. The three letter commands that are used are given below. - Ass - puts you into assembler mode.
- Dis - puts you into the disassembler mode.
- Let - waits for a string to be input. It then outputs the Ascii value of each character in hex and decimal.
- Cal - asks for number then calls the routine at that address.
- Hex - converts a decimal number to hex.
- Dec — converts a hex number to decimal.
When the assembler routine is in use the start address can range from 9000 to 49152 (&C000). When entering data or mnemonics make sure that there is a space betweent he mnemonics and the numbers (which can be entered in decimal or hex). Press enter at the end of every line and to finish assembling press enter again.
The second and final part of the listing will be published next week. PopularComputingWeekly861204 |
