INFRARED



Infrared is a disassembler program written specially for the Sinclair ZX

Spectrum. it gives full Z80 mnemonics (the exception being that after relative

jumps, the destination address is given rather than the displacement) Infrared

is supplied in two different versions for use in either 16K or 48K machines.

Please make sure that you are using the correct version for your machine. If you

have a 48K Spectrum and Ultraviolet, the complementary assembler program from

ACS Software you can have both Infrared and Ultraviolet in memory at the same

time provided that Ultraviolet is loaded first.



To load Infrared use Load. The 16K version loads in three sections so please be

patient. When loading is complete clear the screen and low memory by pressing

any key. The disassembler remains in high memory and can be run with RANDOMIZE

USR 54000 for the 48K version or RANDOMIZE USR 26600 for the 16K version. This

will produce the prompt STARTING ADDRESS? and the address from which disassembly

is to start should be input in decimal. (If you make an error typing in the

address, do not use "delete" - press "E" instead.)



The first 21 instructions, starting at this address will scroll up the screen.

Each line of disassembled listing takes the form of the decimal address of the

first byte of the instruction, followed by the machine code in hexadecimal,

followed by the first 14 characters of the appropriate mnemonic. After a page of

disassembled listing has been given, the program awaits a command. These are:

C - continue disassembly

R - restart disassembler at a new address

P - copy listing to the printer

E - exit to BASIC



Infrared occupies about 6000 bytes, so if you have a 16K Spectrum, you may need

to use SAVE "" CODE x,y and LOAD "" CODE 23760,y to deposit sections of code

into a REM statement y bytes long in low memory.
