Hi,
Is it possible to read sequential file in COBOL using a key.

Hi,

A sequential file can be accessed only sequentially and it is organized sequentially. We cannot read it through a key.

If you want to do some operation for a particular row using the key value which you have assigned, then you have to read the file sequentially and use a "if" or "evaluate" to pick a particular row sequentially.

Again I am insisting there is no way you can read the sequential file using the key.

Thanks & Regards,
Balaji

One suggestion...If the record count is less you can load the seq file into an array and use it as a table..

Sequential File can only be accessed by sequential read.
