last version : The SaveFiles


 Usage :
Screen shows first with *ALL but Jobname = QZDA* : first usage is to work with ODBC jobs.

The first 3 filter fields are for calling the API, they are wilcards values (IE terminated with a *). A * is added at end if missing

The next fields are masks for filtering when reading list of jobs : do not need to add a * at end. A * at end is removed if any.

For all fields, *BLANK = *ALL = *. So, just clear a filter-field witch is not in the filter target.

To sort a column, let the cursor on the column then press F16, such as in WRKACTJOB

Options :

  •  7 runs a WRKACTJOB JOB(jobname). The idea is to provide a way to answer a message. I don't know how to (programaticaly) show a message a job is waiting for a answer, but WRKACTJOB knows. And I know how to run WRKACTJOB. This runs perfectly but when jobname is like QZDASOINIT, all jobs have the same name. In this case, note the job number before runnning option 7, then (when under wrkactjob) F11 two times

  • all other runs WRKJOB. Well know options are runned directly, other runs option 5 :
    • when option = 1 then *STSA 
    • when option = 2 then *DFNA 
    • when option = 3 then *RUNA 
    • when option = 4 then *SPLA 
    • when option = 5 then *SELECT 
    • when option =10 then *JOBLOG 
    • when option =11 then *PGMSTK 
    • when option =12 then *JOBLCK 
    • when option =13 then *LIBL
    • when option =14 then *OPNF 
    • when option =15 then *FILOVR 
    • when option =16 then *CMTCTL 
    • when option =17 then *CMNSTS 
    • when option =18 then *ACTGRP 
    • when option =19 then *MUTEX 
    • when option =20 then *THREAD 
    • when option =21 then *MLBA 
    • other then *SELECT 

known issues

  • crash when jobname not a name (like *ALL*), correction coming soon

WRKJOBR nuggets

wrkjobr is based on well known apis QUS*US, QUSLJOB and QUSRJOBI. OK, no gold here. But I have discover a pretty way when using the user space. After loading the user space, I have declared it as ... a working variable. How ? With a pointer ! The blending of user space and pointer produce a code very clear. code excerpt  :

start with creating a user space in qtemp (no secret)

quscrtus ( Usrspc// get memory for array .../...

then, call the list job API : (no more secret)

qusljob(usrspc : 'JOBL0100' : qjob : cbstatus :errcode )

now, I have a based data structure named LAH (for List Api Header). (it's here the sorcerer had worked)
I give to the pointer the address of the user space. Clearly, I use LAH as a mask to format & read the user space  

qusptrus(usrspc : pLAH);

And Voila ! my LAH work field is now "containing" the user space data : under STRDBG, i can run EVAL LAH
Now, I can use the list as if it is in an array (in fact, it's really an array) 

for iJob= 0 to lah.count - 1;
 pJobL0100 = pLAH + LAH.Data_Offset + iJob * LAH.entry_Size ; 
 // Now, the DS JOBL0100 contains one of the jobs listed by QUSLJOB
 rtvjoba(jobi0200:%size(jobi0200):'JOBI0200':'*INT':jobl0100.Internal_ID:errcode);
 .../...
endfor;

Applause the guru ! (yes i'm very proud of myself. it's not politically correct, but when I am alone in front of my mirror, no one comes to antagonize me, even my reflection, it's to say!)

it's not the end ! there is an other nugget

I have implemented the "F16=sort" with the C-Sort-Array procedure :

For details search the web about QSORT, there are many articles on (first target : SystemINews)
But, to resume, QSORT need

Below, SortArray is the array, and SortBy is the function that sorts 2 elements

some data definitions

// Prototype for qsort - which should be in a /COPY member
D C_QSort Pr ExtProc('qsort') 
D DataToSort * value 
D Elements 10U 0 Value 
D Size 10U 0 Value 
D SortFunct * ProcPtr Value 
 
d SortElement ds 
d qualified 
d based(pSortElement) 
d JOBNAME like(sbJOBNAME ) 
d USERNAME like(sbUSERNAME) 
d JOBNBR like(sbJOBNBR ) 
d CURUSER like(sbCURUSER ) 
d IP like(sbIP ) 
d sts like(sbsts ) 
d SBS like(sbSBS ) 
d SortArray s 65535 based(pSortArray) 
d SortAryNbr s 10i 0 inz(0) 
d SortAryPos s 10i 0 inz(0) 
d SortAryLen s 10i 0 inz(0) 
d SortEltlen s 10i 0 inz(%size(SortElement)) 
 // Constants used by qsort sequencing routines 
D High C 1 
D Low C -1 
D Equal C 0 
 // Prototypes for the sequencing routines used in the program
D SortBySbsJob Pr 10I 0 
D Element1 Likeds(SortElement) 
D Element2 Likeds(SortElement)
d SortBy s * procptr

how to load an element :

// add an element to sort array 
sortarylen+= sorteltlen; 
sortAryNbr+=1; 
pSortArray=%realloc(pSortArray:SortAryLen); 
// prepare last element for update 
pSortElement = pSortArray + SortaryLen - sorteltlen ;
// update the element 
sortelement.jobname= JOBI0600.Job_name ; 
sortelement.username= JOBI0600.User_name ; 
sortelement.jobnbr = JOBI0600.Job_number ; 
sortelement.curuser = JOBI0600.Current_user ; 
sortelement.ip = JOBI0600.Client_IP ; 
sortelement.sts = JOBI0200.actjob_status;

how to sort the elements

SortBy = %Paddr(SortBySbsJob); 
C_QSort(PSortArray:SortAryNbr:SortEltLen:SortBy);

how to unload elements

SortAryPos = 1;
// set pointer to first job
iJob=0; 
// get one job 
if sortARyPos > SortAryNbr;
 // done
 iter; 
endif; 
// * load one line 
pSortElement = pSortArray + ( SortaryPos - 1 ) * sortEltLen ;
sbjobname = sortelement.jobname ; 
sbusername = sortelement.username ; 
sbjobnbr = sortelement.jobnbr ; 
sbcuruser = sortelement.curuser ; 
sbip = sortelement.ip ; 
sbsts = sortelement.sts ; 
sbsbs = sortelement.sbs ;

And the call-back sort procedure for one element :

P SortBySbsJob b 
D PI 10I 0 
D Element1 Likeds(SortElement)
D Element2 Likeds(SortElement)
 /FREE 
 SELECT; 
 // level 1 sort : by sbs 
 WHEN Element1.sbs > Element2.sbs ; 
 RETURN High; 
 WHEN Element1.sbs < Element2.sbs ; 
 RETURN Low ; 
 // next level : by name 
 WHEN Element1.jobname> Element2.jobname; 
 RETURN High; 
 WHEN Element1.jobname< Element2.jobname; 
 RETURN Low ; 
 OTHER; 
 RETURN Equal; 
 ENDSL; 
BEGSR *PSSR ; 
 DUMP ; 
 ENDSR ; 
 /end-free
