Hi All,
If we have an array declared as
01 ARRY.
05 STUDENT PIC 9(06) OCCURS 12 TIMES.
Say, it has all the values declared, now we want to sort this array.....How is it possible. |

On December 10 I posted 2 copybooks that do exactly what you want to do. I asked folks to try them out. Nobody has responded yet which I did not expect because sorting is such a common requirement.
Why don't you give them a try? Based on what you describe you would use them as follows:
In your working storage section:
COPY SORTWORK.
In your procedure division:
COPY SORTPROC REPLACING
==:SUFFIX:== BY MYSORT
==:SORT-SEQUENCE:== BY SORT-ASCENDING
==:SORTROW:== BY STUDENT
==:SORTKEY:== BY STUDENT
==:NBR-OF-ELEMENTS:== BY 12
Read the post on Dec 10 for more details... |
