What are RMS attributes?
Most OpenVMS files are handled by a subsystem known as RMS, for Record Management Services. This part of the operating system allows OpenVMS programs to use optimized file formats for various applications, and yet still be able to read each others’ files. Rarely do users need to concern themselves with RMS attributes, which describe the way the records (chunks of information within the file) are arranged.

Rarely do users need to concern themselves with RMS attributes, which describe the way the records (chunks of information within the file) are arranged. If it does come up, here are a few of the relevant commands: $ ANAL/RMS file See what the RMS attributes of file are. $ ANAL/RMS/FDL/OUTPUT=RMS file Create a file called RMS.FDL that describes the records in file. $ CONVERT/FDL=RMS.FDL file1 file2 Convert the record structure in file1 to match that described in RMS.FDL and put the result in file2. $ SET FILE/ATTRIB=(LRL:1000) file Change one of the RMS attributes of file. $ EXCHANGE/NETWORK/FDL=RMS.FDL file1 file2 Used primarily with files that are in stream-lf or fixed 512 byte record format (both common “binary” formats).
