Name: UNMACRO Author: Robert Thomas Chojnacki Center for Manufacturing Engineering Northwestern University chojnacki@vaxmfg.tech.nwu.edu Operating System: VAX/VMS Source Language: VAX C Keywords: Disassemblers Abstract: Please also read INSTALL.DOC and UNMACRO.DOC. UNMACRO is an interactive disassembler that keeps track of what each byte of the program is (i.e. an instruction, .ENTRY, .QUAD, etcetera). You may leave a session and continue where you left off later by the SAVE and UNSAVE instructions. Features include automatic labeling (for JMP, BR, etc. instructions), automatic .ENTRY (for CALLG, CALLS, transfer address); ability to write the disassembled code to a file; a "DISASSEMBLE UNTIL" that allows disassembly until a data byte, end of the image, or until a specified PC; ability to display any part of the image in DUMP format, ability to display the image header in DUMP format; easily jump from one part of the image to another; SEARCH the image for a byte string; displays important information such as transfer addresses, image base, etcetera. Also knows the P1 system vectors. User defineable symbols for CALLx instructions is included. Commands may be abbreviated and the user may specify that there is no image header, as in the case of boot blocks, etcetera. UNMACRO is not finished but functional. Unfinished parts include most of the .ASCIx directives. A help-format file is included.
