ODTV09: RT-11 DEBUGGING TOOL An extension of ODT, ODTV09 uses the system terminal or an auxillary to display 35 Application Program symbol values and the GPR's R0 to R5 at program breakpoints. Data is encoded to octal/decimal/hex per user option. It creates a user file of AP symbols and searches the link map for their addresses. Non global symbols may be entered via prompts. Repeat debug ses- sions input stored file and updates addresses. Symbol file is altered on command. Display format is 3 columns of 12 rows, spaced for clarity. Each column contains the symbol, value, hi and lo byte values. Two additional rows display R0 thru R5. A dynamic mode allows the AP to run without interruption, updating the display values via the LTC. User may SET/CLR symbol locations or transfer integer values via an accumulator "on the fly". A timed blink cycle monitors AP flag (set/clr) conditions. Single keystroke control of 10 global flags for use in debugging. Global breakpoint and relocation registers enable preload at start up for repetitive sessions. Assembles with/without EIS. Display up- date period is approximately 1 second @9600 baud.
