LISTC clarification

Postby Viswanathchandru » Thu May 17, 2012 10:47 pm

Dear all,

I have a piece of snipet that list the catalog information of a GDG generation file. The code works fine if i give the GDG file inside the code. But, if i fetch the GDG file names from a different dataset through EXECIO command it fails with RC 12. Can anYbodY help me in understanding the reason. Please find the codes below:

 X=OUTTRAP('LST.')           
 "LISTC ENT('"REWIEW.GDG.G0201V00 "') ALL"     
 X=OUTTRAP=('OFF')             
this works fine. But this code

/* REXX */                                               
TRACE ?R                                                 
"ALLOC F(INDD) DS('"REVIEW.DATASET.REPORT"') SHR REUSE" 
 "EXECIO *  DISKR INDD(STEM NEW."                         
 DO I=1 TO NEW.0                                         
X=OUTTRAP('LST.',4)                                       
"LISTC ENT('"NEW.I"') ALL"                               
X=OUTTRAP=('OFF')                                         
where REVIEW.DATASET.REPORT contains 5 GDG's together. Please advice. Apologize if i'm wrong!


Regards,
Viswa

Hello,

Inside the DO loop, where did you specify the dataset name for the listc? It is allocated, but i don't see this referenced in the other code. . .
Hope this helps,
d.sch.

Hello scherrer,

Thanks for addressing the post!. The dataset name is obtained from the stem variable.

If you look at the contents of REVIEW.DATASET.REPORT you should be able to deduce the problem quite quickly.

Show us the trace.

Likely, you need to strip out trailing blanks.

Hello Steve, here is the Trace.

 4 *-* "EXECIO *  DISKR INDD(STEM NEW."                   
   >>>   "EXECIO *  DISKR INDD(STEM NEW."                 
                                                         
 5 *-* DO I=1 TO NEW.0                                   
   >>>   "1"                                             
   >>>   "2"                                             
                                                         
 6 *-*  X=OUTTRAP('LST.',4)                               
   >>>    "LST."                                         
                                                         
 7 *-*  "LISTC ENT('"NEW.I"') ALL"                       
   >>>    "LISTC ENT(' REWIEW.GDG.G0201V00
                       ') ALL"                           
   +++ RC(12) +++

And leading ones, evidently.

Akatsukami, Pedro, steve, Thanks for addressing the post!

As advised i have manually deleted the space i mean the leading ones. Still i get the same. here is the trace.

7 *-*  "LISTC ENT('"NEW.I"') ALL"                         
  >>>    "LISTC ENT('REVIEW.GDG.G0201V00     
                      ') ALL"                             
  +++ RC(12) +++                                         
                                                         
please advice.

It seems you have trailing spaces, as previously suggested. If you strip those away, it'll all fit on one line as well.

Perfect from all! trailing spaces made the problem. Which i didnt notice. i tried leading. but left trailing. Now it works fine. Thanks Scherrer, Pedro,Akatsukami, Steve,Bill for the guidance and support. Thanks again!
