Hi,
Need some help on splitting a huge data set dynamically without losing the groups .
Have a very big data set with the data look like
12abc
12cde
12kgh
23abc
23qwe
23ert
23dfe
.
.
.
Need to split this data set into multiple data sets dynamically without losing the group into 2 different data sets.
First data set should have
12 data
second data set should have
23data
Thanks
Edited to use better terminology - data set instead of file and correct spelling of losing (not loosing which is not a word)
Loosing is a word. File, schmile. |

12 years here and you still haven't used code tags while representing the data? What is that in the requirement is very difficult that you don't understand? Or did you try anything as yet by yourself? And why do you need to break it to multiple?
If you need to create multiple data sets dynamically then did you think of writing a sort card through COBOL program? |

sril.krishy,
Will you always have two output data sets? Or do you expect a dynamic number of groups as well?
Are these values fixed - '12' and '23'? Or can these keep changing?

If we are to write a COBOL (or any other) program, then why write a sort card, why not do the split itself there dynamically? |

as at that point you don't know how many data sets to assign in the output, or do we? |

We don't know that before hand, the program (whichever language used) should do it dynamically. |
