Templates: Procedure tracing template 1998-12-31 -- Roberto Artigas Jr Newsgroups: TopSpeed.Topic.Templates
Editors note: Please note that some lines may wrap in the template code.
Heaveno - Here is some template source for everyone. Add it to your
favorite template chain.
The original idea came from Craig (The Data Ferret) where he posted the
source from a CW2003 Template to save the procedure name to a variable.
I took the idea, expanded it a bit, and used it with ABC templates. This
allows the conditional tracing to a log file of every procedure that you
execute in your logic. The basic idea is to pass the name of the file, app,
procedure, and trace line to a routine, prepend the current date and time,
and write out to a log. You will have to furnish your own
'fnExecTraceProgram' routine. In my case this routine lies in a DLL. Since
the logging routine opens and closes the log file, programs that are
TERMINALLY ILL (GPF's with no clues) will have a trace of the routines that
you have executed up to the routine that has died. At least it is better
than nothing.
You can conditionally remove the logging code and leave the variables. Just
in case you need to pop up some message. Or you can remove both from
generation. This is a very small template. Begining Template persons should
be able deal with it. The only thing that I ask, that if you enhance,
correct, modify, or otherwise improve it, please post it again. That way
all will benefit.
Here is the TEMPLATE.....

#ENDIF
#ENDAT
#!====================================================================
#!
Here is a sample of the 'fnExecTraceProgram' routine. This will NOT compile
since you are missing a variable and an API function call. It is only shown
as an example so you can create your own routine.
fnExecTraceProgram PROCEDURE (strFileName, strProgram, strRoutine, strLogLine)
LIT:Separate EQUATE('|')
LOC:strLine GROUP,PRE(LOC)
strDate STRING(010)
strSep0 STRING(001)
strTime STRING(008)
strSep1 STRING(001)
strProg STRING(008)
strSep2 STRING(001)
strRout STRING(022)
strSep3 STRING(001)
strData STRING(080)
END
TraceFile FILE,DRIVER('ASCII'),PRE(Z0),NAME(LOC:FileName),CREATE
Rec RECORD
LogLine STRING(132)
END
END
CODE
LOC:FileName = CLIP(strFileName)
IF ~fnFileExists(LOC:FileName) THEN ! <<< API >>>
CREATE(TraceFile)
CLOSE(TraceFile)
END
CLEAR(LOC:strLine)
LOC:strDate = FORMAT(TODAY(),@D10)
LOC:strSep0 = LIT:Separate
LOC:strTime = FORMAT(CLOCK(),@T04)
LOC:strSep1 = LIT:Separate
LOC:strProg = strProgram
LOC:strSep2 = LIT:Separate
LOC:strRout = strRoutine
LOC:strSep3 = LIT:Separate
LOC:strData = CLIP(strLogLine)
!STOP('FileName=''' & CLIP(LOC:FileName) & '''')
OPEN(TraceFile)
IF (ERROR()) THEN
STOP('fnExecTraceProgram: ' & ERROR())
RETURN
END
CLEAR(Z0:Rec)
Z0:LogLine = LOC:strLine
APPEND(TraceFile,CLIP(Z0:LogLine))
CLOSE(TraceFile)
RETURN
Enjoy!
