Hello,

Whats the maximum allowable LRECL of a variable length(VB) file..?

We can use the FB file to store maximum of 24K length record.

I need to use some file to store more than 15Million characters in a single record. Is it possible..? Please advice..?

LRECL Parameter from the z/OS V1R9.0 MVS JCL Reference.

Spanned Format-VS Records (Sequential Access Method) from the z/OS V1R7.0 DFSMS Using Data Sets guide.

A FB record is not limited to 24K length.

What could possibly be the reason for this design? How could a program read or write such a record?

XML parsing, for one. Reading and writing is a zebra of another color, though.

I need to store a array with 25 character length for 9000 times and that should be in a single record. Because the progam will append 25 bytes for every loop and read it character by character at the last step of the program.

Hello,

I suggest you consider a design change.

What you need to do should be rather straightforward using vsam or a database table.

Unless there is more to the requirement than you have posted. . .
