Hi,
I tried to use PL/I builtin function "DATETIME" to get year part alone but it shows some junk.
| Code: |
PGMSAM01: PROC OPTIONS(MAIN) REORDER;
DCL W_MY PIC '9999';
W_MY = SUBSTR(W_MY,1,4);
PUT SKIP LIST('YEAR = ',W_MY);
END;
|
Please let me know where I am going wrong and how to get year part alone.
Thanks. |

Try invoking the DATETIME function  |

Hi,
Thanks........I tried this too but did not work either 
| Code: |
PGMSAM01: PROC OPTIONS(MAIN) REORDER;
DCL W_MY PIC '9999';
W_MY = SUBSTR(DATETIME,1,4);
PUT SKIP LIST('YEAR = ',W_MY);
END;
|
Result:
| Quote: |
YEAR = 000000+0.0E
|
Please help. |

nowhere in Your code is present a proper invocation of the PL/I datetime function
did You ever hear about manual reading ? 
start her to meditate on the PL/I manuals relevant for Your PL/I version
www-03.ibm.com/systems/z/os/zos/bkserv/zappls2.html
and here is a tested snippet
| Code: |
****** ***************************** Top of Data ******************************
000001 zmf05:
000002 Proc Options(Main);
000003 dcl date char(17);
000004 dcl year char(4);
000005 put skip list('ZMF05 Started');
000006 date = datetime();
000007 year = substr(date,1,4)
000008 put skip list('date =',date ); ;
000009 put skip list('year =',year ); ;
000010 put skip list('ZMF05 Ended');
000011 End ;
****** **************************** Bottom of Data ****************************
|
to produce as per manual
| Code: |
********************************* TOP OF DATA **********************************
ZMF05 Started
date = 20120208205001481
year = 2012
ZMF05 Ended
******************************** BOTTOM OF DATA ******************************** |

And you got RC=4 or RC=8 from the compile, depending if you had RULES(LAXDCL) or RULES(NOLAXDCL), didn't you?
A built-in function that is not declared BUILTIN must be invoked with an argument list -- even if that list is empty -- or the compiler interprets it as an AUTOMATIC variable. Look at the Attribute Table; I'll bet you see DATETIME as an implicitly-declared DEC FLOAT (6).
Try this:
| Code: |
PGMSAM01: PROC OPTIONS(MAIN) REORDER;
DCL W_MY PIC '9999';
W_MY = SUBSTR(DATETIME(),1,4);
PUT SKIP LIST('YEAR = ',W_MY);
END;

Gentlemen,
Even is DATETIME is treated as a FLOAT(6) due to using "rules(laxdcl)", it is assigned to a PIC '9999' and the latter will never ever be printed in a float format using "put list'...
The OP has clearly not provided us with a true copy of the failing code. (Oh, what a surprise...) |

Oh, to be sure the TS is talking out of his nether orifice. However, between you and Dr. Sorichetti -- and I do myself the honor of suggesting that I may write a word worth reading now and again -- I believe that there is enough PL/I expertise on this board to point out how a sotfware engineer baked the dog and what he should have done instead, despite his best efforts to obfuscate the issue. |

just checked ( yep... curiosity killed the cat )
| Code: |

000005 put skip list('w_my =',w_my ); ;
000006 End ;
****** **************************** Bottom of Data **************************** |
the results ( the interesting part at least )

Hi Akatsukami, thanks it worked and I got expected results.
Dr. Enrico, thanks for pointing me to some good PL/I stuff......I searched internet for hours but found nothing on DATETIME function
Thanks. |

Hi,
| Code: |
********************************* TOP OF DATA **********************************
YEAR = 2012
******************************** BOTTOM OF DATA ********************************
|
May I know why value "2012" appears at far end than near "YEAR"? If I want to use this value against a year field in my embedded SQL in my PL/I program, can I use it?
Thanks. |

| You searched the internet for hours? Why? The information is in the language reference nanual for PL/1 -which is readily accessible from the links aty the top of each page in the forum. Suggest you look there (or the user guide) for the answer to why your date is TABbed over to the right. |

You can specify the format of the result with DATETIME.
DCL YEAR CHAR(04);
DCL DATETIME BUILTIN;
YEAR = DATETIME('YYYY');
Either declare builtin functions or use parenthesis. WIth parenthesis DATETIME will be recognized as Builtin Function.
DCL PIC4 PIC'9999';
PIC4 = DATETIME('YYYY');
To convert character value directly to picture variable is not an recommendet programming style. It will produce an library call for conversion.
If you need the year as numeric value better specify
PIC4 = PICSPEC(DATETIME('YYYY'),'9999');
This should be done by inline conversion.
With kind regards
Michael |
