Hmmm. I am heavily dependent on the J debugging system. I believe that I would never have come this far without it.
The thing is, I tend to write J scripts in a verbose way and to give you an idea, here is a sample script which takes data from an MS-SQL stored procedure and returns a heterogeneous array for use by a C# application. NB. ========================================================= NB.*syncArticles (v) synchronizes articles against bom details NB. NB. y is name of articles and BOM NB. returns a converted array syncArticles=: verb define NB. STEP 1: Get the passed parameters 'articles bomdetails'=. 2 take y 'artf artv'=. 2 take articles 'bomf bomv'=. 2 take bomdetails NB. STEP 2: First pass, remove all non matching details header=. 2 drop take bomv NB. NOTE: Use this code if your using the DESCRIPTION arts=. ravel curtail (1 colsfrom artv) atop tomatrix header NB. This code is using the COLOR_CODE NB. arts=. ravel curtail (searchLOOKUP format each 1 colsfrom artv) atop tomatrix header NB. Update the local variable with valid data mask=. increment indices header in arts bomv=. (2 take rank 1 bomv) aside drop arts atop mask colsfrom 2 drop rank 1 bomv NB. STEP 3: Second pass, rearrange the data columsn header=. 2 drop take bomv NB. Make sure that we remove the non matching articles mask=. increment bx not arts in header if. tally mask do. fxart=. arts replacecols mask;0 else. fxart=. arts end. NB. We reorganize the columsn mask=. ((box header) indexof every fxart) result=. (2 take rank 1 bomv) aside arts atop drop mask colsfrom 2 drop rank 1 bomv NB. Now convert to a valid format for C# boxedlist2mat numbers2sqldata bomf;result ) You see, for me, the debugger is an indispensable tool when debugging complex J application. r/Alex -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Björn Helgason Sent: Thursday, December 20, 2007 12:54 AM To: Beta forum Subject: Re: [Jbeta] Deleting temporary files I decided I wanted to give debug a go Started debug and set the stops on the moo verb load 'c:\users\bjorn\j602-user\temp\1.ijs' 13!:3 '* 0:0' moo 10 10 10 10 |stack error *coname[0] I can not remember any case where debug has helped me nor trace for that matter I love the trace and being able to step through C in the visual studio If anything similar could be done involving J I would really love it A beautiful application like moo is very few lines but lots of operations on each and it would be marvelous to be able to see it in action step by step 2007/12/19, Björn Helgason <[EMAIL PROTECTED]>: > > I have to say that I may have misunderstood the project manager. > I may have tried it a long long time ago and it did not help me then. > > If it will help with debug and trace I am all for it. > > As much as I like to perform trace and debug in C the debug in J I > have never been able to let it perform the way I want it. > I more or less wind up with sticking smoutput here and there in the > code instead. > > I do like to create scripts and let them build up gradually and I > never keep them in temp unless I want them to accidentally disappear. > > I do use a lot of files in temp but only temporarily and I always > expect temp stuff to not contain anything of permanent value. > > 2007/12/19, Chris Burke < [EMAIL PROTECTED]>: > > > > Oleg Kobchenko wrote: > > > It would be useful if interested J users would share their order > > > of use cases for J environment.
