Reply with quote

Hi Friends,

I have a file contains many records. But I have some of the records in between other records.

Now, i want to SORT only required records - Say- if records contains 'DELETE' at some fixed position, then only these records should be sorted and written out into the output file. All other records should be written into the output file as it is without sorting.

Example: Input file

AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPICRWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIDRWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIXRWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIBRWD
AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPILRWD
AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPIGRWD

After Cobol Internal Sort, The output file should be as follows:

AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIBRWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPICRWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIDRWD
AAAAAA 12345 DELETE &BMEDPAC.KW894BC.KPIXRWD

AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPIARWD
AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPILRWD
AAAAAA 12345 STEPS &BMEDPAC.KW894BC.KPIGRWD

Could any one of you please help me with the COBOL coding.

Thank You.

Hello,

What should happen when, after the AAAAAA set of records, there is a BBBBBB set of records. Is your requirement that all of the A's stay together or should all of the DELETEs be put together.

Please expand your input/output to include at least one more "set" of records.

The good news is that to do what you want will not be difficult once the rules are understood icon_smile.gif

Other than the "BOLD"ing, is there a difference between the input file and the output file?

Yup, notice the sequence change in the DELETE records. . .

Hi dick scherrer,

Thank You for your response. In the example I have mentioned, there is no problem if I have another set of records as BBBBB.
Only I need is all steps that are having DELETE should be sorted for the datasets followed by DELETE. Rest of the records should be written to output file as it is without change.

Hello Harsh,

I don't believe i follow your most recent post. This

has me confused. . .

Please post your original input data and a set of BBBBBBs as a new input file and the desired output from the expanded input sample.
