Hi
I need immediate help from you on removing the lines between Low and High values.
For example I have a dataset like
abc1254.01.12.37
abc1254.01.12.38
abc1254.01.12.39
abc1254.01.12.40
abc1254.01.13.13
abc1254.01.13.14
abc1254.01.13.15
abc1254.01.13.16
In this i want to delete the Lines between Low and High value.
The final o/p should be like
abc1254.01.12.37
abc1254.01.12.40
abc1254.01.13.13
abc1254.01.13.16
Please help me on this. Thankyou.

How are you "grouping" the records? By positions 1-13, or some other way? How exactly?

What is the RECFM and LRECL of the input file?

Are the input records already in sorted order as shown in your example?

No the records are not in sort order, i thought to apply the sort function before grouping records by position 1-16 chars
Input file of Recfm FB of length 80.

i thought to apply the sort function before grouping records by position 1-16 chars

If you group the records by 1-16, then the low value would be:

abc1254.01.12.37

and the high value would be:

abc1254.01.13.16

but that's not what you show as the expected output. You need to do a better job of explaining the "rules" for getting from input to output before anyone can help you.
