What are the limits on file specifications and directories?
A file specification has an aggregate maximum size of 255 characters (NAM$C_MAXRSS) at present, assuming ODS-2 limits and traditional DCL process parsing settings (SET PROCESS/PARSE_STYLE). The node and device specification may be up to 255 characters each- file name and file types may be up to 39 characters each. File versions are from 1 through 32767, though 0 (latest version), -0 (oldest version) and -n (n’th previous version) can be used in most contexts. A file specification may not have more than 8 directories and subdirectories or-with a rooted directory, two sets of eight are possible-and while it is possible to create subdirectories of greater depth, accessing them under ODS-2 is somewhat problematic in most cases, and thus should be avoided. Under ODS-5 with extended DCL parsing (SET PROCESS/PARSE_STYLE), the filename length limits are up around 4,095 (NAML$C_MAXRSS) characters, and directories can be around 255 levels deep. Application developers should use OpenVMS-supplied
