I have a requirement where i have to get the current time in a ps file if current time is less then 5 pm CT(central time)i need to execute the 2nd step in jcl or if the current time is more than 5 pm i need to execute the 3rd step in jcl.
Is it possible through sort card to get the time and do this..? I wanted to achieve this using sort only if possible any hint is fine. |

Yes, it is possible. Though not only single "SORT card" must be involved.

The major hint is: RTFM.
Pay attention to various &DATExxx parameters, and also Y4*,DTNS=(abc) and Y2*,DTNS=(abc) date conversion operations.
In order to skip or to execute next JCL step the best way is to conditionally place a dummy record into a temporary output via
OUTFIL INCLUDE=(compare dates),NULLOFL=RC4
In the next JCL step you can check the result of this comparison:
// EXEC PGM=...,COND=(4,EQ,SORTSTEP)
or you can use JCL IF statement:
// IF (SORTSTEP.RC EQ 4)
// ... do one thing
// ELSE
// ... do another thing
// ENDIF |

Hi I have used below sort card to get the timestamp:
| Code: |
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL REMOVECC,NODETAIL,
HEADER1=(C'TIMESTAMP=',TIME=(12.))
/* |
My output file looks like:
| Code: |
************************
TIMESTAMP=11.37.26 pm |
Now i want to compare it with 5:00:00 Pm if it is greater than or less then 5 pm ...do i need to convert this file in character format, ned bit help here how i can compare here. Actually looking for belwo point you mentioned.
OUTFIL INCLUDE=(compare dates),NULLOFL=RC4
how this step works..? how i can put compare condition here ,,? can i simply compare fields against 5:00:00 pm ..? |

I understand that your requirements are for a 5 pm boundary: regardless, in this situation, I would still worry about date boundaries.
Is 00:00:01 am greater than 12:59:59 pm?
For that reason, I think you should consider using the date also. And using military time instead of am/pm might be an easier comparison. |

I am not sure about this how it works..?
I am not worried about the date part i only want to compare the time if it is greater than 5:00:00 pm or less than it.

If you were to run that sort step at exactly 5 pm, you would get:
| Code: |
*******************
TIMESTAMP=17.00.00 |
Working out the comparison sort card should be simple.

Your input file has periods between the hours, minutes and seconds. Your sort card has colons in those locations.

Under no circumstances the value C'02.57.29' can be correctly compared to C'17:00:00'
PS: You've lost the critical parameter NULLOFL=, required for your initial task!
PPS: As mentioned in previous posts, the correct tool for your task is - any scheduler software, not SORT utility. |

| Is it possible that you only need to compare the first two characters of the time? |

Yes , I am thinking of that option it is in 24 hr format I could take only 17 in consideration. i am avoiding scheduling because number of jobs will be increased to maintain so thought of doing it using sorting itself.
Please suggest me a good option here since we are close to this if I can compare the only first two character of time..? |

re: only first two characters
only guessing at the syntax. Please verify.
| Code: |
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL FNAMES=SORTOUT,INCLUDE=(11,2,CH,GT,C'17')
/* |

Same result after
| Code: |
//SYSIN DD *
SORT FIELDS=COPY
OUTFIL FNAMES=SORTOUT,INCLUDE=(11,10,CH,GT,C'17.00.00')
//* |
P.S.
The major issue with this topic was: how to use the parameter NULLOFL?
All the rest is too trivial to discuss further. |
