MPE/iX and POSIX Differences
Filename Size Restrictions
have a maximum of 255 characters.
For more information, refer to the New Features of MPE/iX: Using The Hierarchical File
System Reference Manual for accepted syntax of file names and directories.
NOTE The file identifiers “./FILENAME” and “./filename” refer to two different files
in the POSIX name space since character case is accepted in the POSIX name
space.
Example 1:
Files in the MPE file domain in PUB.SYS (MPE syntax) are also viewed as being a part of
the POSIX file domain in /SYS/PUB/ (POSIX syntax).
:listf log@.pub.sys
FILENAME
LOG LOG0112 LOG0113
or
:listfile /SYS/PUB/LOG@
PATH= /SYS/PUB
LOG LOG0112 LOG0113
Example 2:
Files in the POSIX file domain in “/SYS/PUB/directory1/directory2/” (POSIX syntax)
are outside of the MPE file domain.
:listf /SYS/PUB/directory1/directory2/
File name missing. (CIERR 531)
:listfile /SYS/PUB/directory1/directory2
PATH= /SYS/PUB/directory1/
directory2/
PATH = /SYS/PUB/directory1/directory2/
TESTDATA
NOTE The MPE listf command executes against files in the MPE file domain. The
MPE command listfile created for POSIX executes against files in both the
MPE and POSIX file domains.
