Hi,

I have the below file. I have a key in first record as 21810. Similarly you can see as 21811 & 21812 down.

Can I merge my first 4 records to a single record with different LRECL ?.

Code:

                                                               
                                06F77400015908476     21810                   1*
 0559002GR GGL25L-CWZGBA  032317H 2BZMCA0055900021317                         B2*
 0083LC30                                                                       
 06    20170213                                                                 
                                06F82400015908475     21811                    1*
 0559002GR GGL20L-CWZGBA  032317H 2ZZMCA0055900021117                         B2*
 04U7LA40                                                                       
 06    20170211                                                                 
                                06F72600015908473     21812                    1*
 0559002GR GGL20L-CWZGBA  032317H 2ZZMCA0055900021017                         B2*
 01J4LB23                                                                       
 06    20170210

You have a data set. And, yes, you can. Read up on RESIZE.

1) The term "merge" (especially in SORTing environment) has a different meaning; the MERGE operation is applied to the process of merging records from several pre-sorted datasets/files into one sorted output dataset/file.

What you need is described better via the term "concatenate", or "append" several records in one single resulting record.

2) The value of LRECL is an attribute of created dataset; it has a very little relation to the operation of records concatenation; you are likely talking about concatenated record size.
LRECL of a dataset can be changed even without record concatenation, and vice versa: record concatenation can be performed while leaving the dataset LRECL unchanged (especially with RECFM=VB, but RECFM=FB too).
