Hi All,
My requirement is : I have a ps file and it has 8 record and one record that is 5th record in file is stud_id in my rexx i want to use this stud_id and fetch student name and want to append this stuent name at the end of the same input file which we are reading.
I am able to fetch the stud_name from db2 into a variable now i want to add this stud-name at the end of the file this same file. How i can acchive this any hint or syntax would be great as i dnt carry much experties here in rexx.
Thanks |

Using EXECIO and the stack:
| Code: |
"EXECIO * DISKR ddname (FINIS)" /* puts records on the stack */
queue new-record
"EXECIO" queued()" DISKW ddname (FINIS)" /* rewrite dataset from the stack */ |
or use a stem instead of the stack. |

Hi
Thanks for reply.
I am using below syntax to write the data into new file
| Code: |
outline.1 = prjval
"EXECIO 1 DISKW DD02 (STEM outline.1 FINIS"
return 0;
but getting below error my outline.1 has right data
>>> "EXECSQL CLOSE C1"
84 *-* outline.1 = prjval
>>> "P0007809"
85 *-* "EXECIO 1 DISKW DD02 (STEM outline.1 FINIS"
>>> "EXECIO 1 DISKW DD02 (STEM outline.1 FINIS"
+++ RC(-3) +++
86 *-* return 0
>>> "0" |

Also when i used your logic .
getting below erro
| Code: |
86 *-* queue prjval
>>> "P0007809"
87 *-* "EXECIO" queued()" DISKW dd01 (FINIS)" /* rewrite dataset from the
>>> "EXECIO 2 DISKW dd01 (FINIS)"
+++ RC(-3) +++
89 *-* return 0
>>> "0"
J56500I COMMAND P0007809 NOT FOUND
J56500I COMMAND P0007809 |

| You probably are not in the right environment for EXECIO. |

| Are you having an address command somewhere before? |

Well, you must have changed the environment somewhere.
Verify by doing SAY ADDRESS()
To fix the problem, put ADDRESS TSO in front of the EXECIOs. |

In your stack example, you had a syntax error in the EXECIO statement. It should not have the right paren. And because of that error, you leave something in the stack and rexx tries to process the stack after your exec ends. The stack does not have a valid TSO command, so you get the 'not found' message. |

In your earlier try, you are using a stem. In the code shown:
| Code: |
| "EXECIO 1 DISKW DD02 (STEM outline.1 FINIS" |
you should provide the name of the stem only (without the trailing '1').
This assumes that you allocated the DD02 file with DISP(MOD)
| Code: |
newrec.0 = 1
newrec.1 = new-record
"EXECIO * DISKW DD02 (STEM newrec. FINIS" |

A right paran in EXECIO is perfectly fine, I do it all the time.
I tried the following
| Code: |
outline.1 = 'Just testing'
"EXECIO 1 DISKW DD1 (STEM outline.1 FINIS)" |
it wrote 'OUTLINE.11' to the dataset. Clearly not what I intended, but did not cause a syntax error either.
I will maintain that the RC -3 is caused by a wrong environment, it must be TSO or CMD as far as I am aware. |

| There is that "EXECSQL CLOSE C1" thing inside your EXEC. Please do what Willy has suggested and add ADDRESS TSO before the EXECIO command. |

The option STEM in this example is using OUTLINE.1 as a stem name, not variable name. Since exactly 1 output record is requested, the (incorrect) "stem name" OUTLINE.1 is extended with the first number of element, e.g. number 1, producing OUTLINE.11 which value might be either string "OUTLINE.11", or empty string "", depending on the way the OUTLINE stem is defined - outside of the presented scope of code.
The correct way to specify a stem for output is:
| Code: |
| . . . . (STEM OUTLINE. |
Please, RTFM carefully!!! |

| Well, lets see. I assume the EXECSQL establishes a DB2 environment without properly restoring the previous state. |

Thank you, guys, ,
It worked there were syntax errors and i fixed it , and made my code lil bit clearer by calling para.
Thanks Again |

There is no PARA in REXX; it is not COBOL.
REXX code may be divided into FUNCTIONS, and PROCEDURES. |
