I have a problem statement. I am trying to dump decimal float fields (field not defined in COBOL but in C) from M/F to some other PS file but they are displaying as junk characters. The way these fields are stored in prduction VSAM files, they can be converted to date timestamp using a formula = (((A1/60)/60)/24)+DATE(1970,1,1)+(-5/24)
| Code: |
START_DATETIME END_DATETIME
8/DFL 8/DFL
(116-123) (124-131)
18--------------------- 19---------------------
********************** TOP OF DATA **********************
0.000000000000000E+00 0.000000000000000E+00

1.459084043818478E+09 1.459084043855324E+09 |
Conversion sample below-
| Code: |
Start_Datetime Start_Datetime after using above formula
1.458237600498944E+09 3/17/2016/13:00:00.499
1.458237600521761E+09 3/17/2016/13:00:00.522 |
Please let me know if anyone has ever written JCL for this conversion. |

no...
because nobody with a bit of good judgement would use a float to represent a date! |

This was a really bad idea, not only because, as Dr. Sorichetti says, storing a date as a floating-point is itself a bad idea due to rounding issues, but because different platforms may store floating-point numbers differently.
I don't think that *Sort (and of course you're talking about *Sort, not JCL) can do this kind of calculation; you'll probably have to write a programette. |

No - because JCL does not mess with data. It tells the system that you want to execute a program and what resources that program needs.
You shuld also present your data using the code tags. I will do that for you this time - and lock the topic. |
