12 ;"Notes: HOW DOES IT ALL WORK?
13 ;"
14 ;"Here is how the system fits together:
15 ;"
16 ;"Below is what happens in the CONTROLLING job
17 ;"=================================================
18 ;" -- LaunchIntr^TMGIDE5(JobNum) sets up a signaling global and then
19 ;" creates a 'mupip intrpt JobNum', then starts listening
20 ;" in Controller^TMGIDE3 for communication from the interrupted job.
21 ;" (See below about how this communication gets started)
22 ;" -- Controller^TMGIDE3 polls a communicating global location and can talk back
23 ;" and forth with the other job. When it gets a message to
24 ;" DO TRAP %ZPOS, it then calls STEPTRAP^TMGIDE2, and returns
25 ;" the result of that function back to the other job.
26 ;" -- STEPTRAP^TMGIDE2 is the same interface as the prior debugger. It shows
27 ;" the code, allows the user to move around, and interact
28 ;" with the code. If the user wants to query variables
29 ;" in the other process, then a message is sent out, and
30 ;" a copy of that variable is passed back here for display.
31 ;" If the user wants to modify the other environment, then
32 ;" arbitrary M code can be entered by the user, and it is passed
33 ;" to the other job for execution in that job process space.
34 ;" When ready to execute the next line of code, then STEPTRAP
35 ;" quits with a result signalling a zstep INTO or OVER.
36 ;"
37 ;"Below is what happens in the OTHER job
38 ;"=================================================
39 ;" -- mupip intrpt JobNum --> causes the specified job to execute the code
40 ;" stored in $ZINTERRUPT. For VistA (or if setup in
41 ;" in an environmental script during GT.M launch), this
42 ;" code is to run JOBEXAM^ZU (slightly customized)
43 ;" -- JOBEXAM^ZU --> looks for signaling global, and if found runs INTERUPT^TMGIDE5
44 ;" -- INTERUPT^TMGIDE5 --> sets up $ZSTEP and then calls ZSTEP INTO and
45 ;" quits out of the $ZINTERRUPT code.
46 ;" -- ZSTEP --> causes GT.M to execute the code in $ZSTEP before performing
47 ;" the next line of mumps code for the program that was
48 ;" running at the time the interrupt request was received.
49 ;" -- $ZSTEP holds instruction to run $$STEPTRAP^TMGIDE4($ZPOS)
50 ;" -- STEPTRAP^TMGIDE4 --> sends message to CONTROLLING JOB and waits for reply.
51 ;" Reply will either be a request from the user for more
52 ;" information from this job, or a final reply that allows
53 ;" execution to continue, either by a step INTO, OVER, or
54 ;" a plain ZCONTINUE (which will stop further code-stepping)
