Hi Charan,
In Visual COBOL we removed all of the Micro Focus proprietary files with extensions like .int/.gnt/lbr and rebuilt them as standard .dlls. That is why utils.lbr is now utils.dll.
We moved most of the functionality that was in previous versions of utils.lbr directly into the COBOL Run-time system so chances are it is no longer required.
If you change your calls from call "UTILS.LBR" to simply call "UTILS" then it will load the utils.dll version in case it is required.
