Hi All,
I have the requirement to modify the share options to (2,3) for hundreds of Parm cards.
I'm able not to handle this situation since people can code it multiple of ways similar to below.
Below are few possible ways of coding the share options which i identified so far.
Input can be any of the below format.
Ex 1: SHR (3 3) -
Ex 2: STAGE SHR (1 3) NERAS -
Ex 3: SHAREOPTIONS(2 3) -
Ex 4: SHR(3,3) -
EX 5: SHR (1,3) -
Output should be like this (If share options are not 2 3 then need to change to 2 3):
Ex 1: SHR (2 3) -
Ex 2: STAGE SHR (2 3) NERAS -
Ex 3: SHAREOPTIONS(2 3) -
Ex 4: SHR(2,3) -
EX 5: SHR (2,3) -
There are many ways people can code the share options but my requirement is to identify share options and modify/rewrite the share options to SHR (2,3).
Please someone can help me to fix this.
**I did google for any example before posting but no luck. My apologize if it is duplicate**. |

| What have you tried? What problems do you face? Surely it is simple enough - you only have to check each record for either SHR or SHAREOPTIONS and then overlay the current option with the new option. And don't forget to write an audit report. |

Hint: try to use REXX statement PARSE
You may also need to use other accompanying statements, like: If, Else, Do, End, Call, something else.
P.S.
A ready-to-use code for your own job can be provided at extra charge. |

You can use IEBPTPCH to UNLOAD the Library. In the PS Dataset use a simple Edit with RegEx to change the SHAREOPTIONS parameter to 'SHR (2 3)' or whatever is needed. Final Step is to rebuild the Library using IEBUPDTE.
To find the possible variants of SHR/SHROPTIONS parameter try the following RegEx:
| Code: |
| f r'(SHR|SHAREOPTIONS)[ ]*\([ ]*[1-4]([ ]+|[ ]*,[ ]*)[34][ ]*\)' |

Thank for your reply Nic.
The process which we tried:
1. Find the SHR or SHAREOPTIONS and delete the line.
2. add the new line with SHR (2,3).
Logic to delete:
STRINGA='SHR'
STRINGB='SHAREOPTIONS'
PARSE VAR LINE VAR3 '(' VAR4
IF VAR3 = STRINGA | VAR3 = STRINGB then do
ISREDIT "DELETE &J"
LASTLN = LASTLN - 1
END
END
Logic to add the line after NONINDEXED/INDEXED/NUMBERED:
"ISREDIT LINE_AFTER " LN "= DATALINE" ATTR1
LN = LN + 1
LASTLN = LASTLN + 1
The above logic will not work in below scenario since we need capture the left and right attributes and not able to proceed further.
STAGE SHR (2 3) NERAS -
Please help me to fix this |

If the library members have not been strictly normalized, some lines with SHR/SHAREOPTIONS may also contain other parameters; they all will be silently lost after applying this approach. |

I seem to recall that DEFINE CLUSTER parameters can be abbreviated. Perhaps there may be more abbreviations that you have not yet seen. Look for SHA as a word prefix.
Please correct me if I am wrong about the abbreviations. |

Joerg,
I tried to invoke your command thru rexx but it's not working.
| Code: |
ADDRESS TSO
ADDRESS ISREDIT
ISREDIT "c r'(SHR|SHAREOPTIONS)
[ ]*\([ ]*[1-4]([ ]+|[ ]*,[ ]*)[34][ ]*\)' 'SHR (2 3)' all" |
I'm not even getting any error.
Coded for you |

This works for me.
| Code: |
/* REXX */
address "ISREDIT"
"macro"
"c r'(SHR|SHAREOPTIONS)"!!,
"[ ]*\([ ]*[1-4]([ ]+|[ ]*,[ ]*)[34][ ]*\)' 'SHR (2 3)' all"
exit |

@Pedro: Abbreviations for the IDCAMS keyword can be included in the Edit Change command. Should not be a bigger problem.  |

Thank you Joerg.
I tried with input
| Code: |
000001 SHR (3 3) -
000002 STAGE SHR (1 3) NERAS -
000003 SHAREOPTIONS(2 3) -
000004 SHR(3,3) -
000005 SHR(2,3) -
000006 SHR(4,3) -
000007 SHR(4,4) -
000008 SHR(3,3) -
000009 SHR (1,3) -
000010 SHR ( 3 4 )
000011 SHR (3 , 4 )
000012 SHAREOPTIONS ( 1 , 4)
000013 SHAREOPTIONS ( 2 , 1)
000014 SHAREOPTIONS ( 1 , 2)
000015 SHAREOPTIONS ( 1 , 3)
000016 SHAREOPTIONS ( 4 , 4)
000017 SHAREOPTIONS ( 2 , 4)
000018 SHAREOPTIONS ( 4, 3)
|
Output:
| Code: |
000001 SHR (2 3) -
000002 STAGE SHR (2 3) NERAS -
000003 SHAREOPTIONS(2 3) -
000004 SHR(3,3) -
000005 SHR(2,3) -
000006 SHR(4,3) -
000007 SHR(4,4) -
000008 SHR(3,3) -
000009 SHR (2 3) -
000010 SHR (2 3)
000011 SHR (2 3)
000012 SHR (2 3)
000013 SHAREOPTIONS ( 2 , 1)
000014 SHAREOPTIONS ( 1 , 2)
000015 SHR (2 3)
000016 SHR (2 3)
000017 SHR (2 3)
000018 SHR (2 3) |
Only few got changed. Looks like the code is not working if there is no space between SHR and '('.
Below is the example:
| Code: |
000004 SHR(3,3) -
000005 SHR(2,3) -
000006 SHR(4,3) - |
Coded for you |

| Might be because of different Codepages. Please replace !! with || in your Change command to concat both strings without an additional space. |

Hi Nic & Joerg,
I also tried different approach.
| Code: |
STRINGA='SHR'
STRINGB='SHAREOPTIONS'
PARSE VAR LINE VAR3 '(' VAR4 ')' VAR5
IF VAR3 = STRINGA | VAR3 = STRINGB then d
NEWLN = ' '
NEWLN = VAR3||'(2,3)'||VAR5
NEWLN = STRIP(NEWLN)
END
IF VAR3 ¬= STRINGA | VAR3 ¬= STRINGB then do
LN4 = SUBWORD(VAR3,1,1)
LN5 = SUBWORD(VAR3,2,1)
LN6 = SUBWORD(VAR3,3,1)
END
IF LN5 = STRINGA | LN5 = STRINGB then do
NEWLN = ' '
NEWLN = VAR3||'(2,3)'||VAR5
NEWLN = STRIP(NEWLN)
END |
I'm trying to replace the the values present between ( ) to (2,3) and storing in a NEWLN variable.
I'm using below logic to write the line but getting error " Invalid variable name " .
| Code: |
ATTR3 = NEWLN
"ISREDIT LINE_AFTER " LN "= DATALINE" ATTR3
LN = LN + 1
LASTLN = LASTLN + 1
"ISREDIT SHIFT ) " LN P1-1
******************************************************************************
* *
* Command in error . : ISREDIT LINE_AFTER 9 = DATALINE SHR (2,3) *
* *
* Invalid variable name *
* Name may be 1-8 alphanumeric characters long; first character not numeric. *
* *
* Error message ID . : ISRE121 *
* *
* Last return code . : 20 *
* *
* Macro executing . : MACROH *
* *
* Press ENTER key to terminate the macro. *
* *
* *
* * |
Coded for you - do it yourself from now on |

| You were asked to use the code tags - you did not. Ignoring requests to present your data properly leads to your problem being ignored. Use them from now on or have the topic locked. |

Thank you Joerg. It worked. Please help what is the issue with other code.
Hi Nic,
I will make sure to use the code tags from now. |

Can you guess what will happen if LINE contains:
| Code: |
| FILE(XYZDD) SHR(3 3) - |

FYI, the correct syntax is:
| Code: |
| "ISREDIT LINE_AFTER " LN "= DATALINE '" ATTR3"'" |

Hi Marso,
Actually Nic suggested the below approach but i'm not able to do it.
*****you only have to check each record for either SHR or SHAREOPTIONS and then overlay the current option with the new option. And don't forget to write an audit report.*****
Thanks a lot once again. |

I suggest to keep a backup copy of the data set then use Superc to compare the new and the old. The list of changes is your 'audit report'. |

Sure, Pedro and also thanks for the suggestion.
Please let me know if you can help with any REXX code to compare the PDS members and write a report. We are changing around 1000 parms. |
