CI enhancements introduced in MPE/iX Release 6.0 are the following:

POSIX filenames support additional special characters.
COPY command was enhanced.
SHOWVAR command was enhanced.
New CI evaluator functions were added: ANYPARM(), BASENAME(), DECIMAL(), DIRNAME(), FQUALIFY(), FSYNTAX(), and XWORD().

Details for these enhancements are found in the article, "6.0 CI Enhancements," in chapter 10, "Technical Articles."

CI enhancements introduced in MPE/iX 5.5 Express 3 (C.55.03) are the following:

The LISTF and LISTFILE commands allow users to discover who is accessing files on their system, including remote accessors. LISTFILE output can now be filtered by selecting files based on access type or file code.
Two new CI variables were added: HPLASTSPID and HPSPOOLID. Both contain the spoolfile ID in the form: Onnnnnnn.
The FLABELINFO intrinsic and FINFO() function are able to return the number of sectors and extents a file occupies, file creation time, and the number of accessors to a file.
The PAUSE command can now wait for one or more jobs to complete, to change state from waiting to executing, or to begin execution.
The INPUT command allows the number of characters to read from $STDIN to be specified.
The PRINT command is now able to display all data in a file, even if this data appears to be line numbers. The new NONUM option enables this feature.

Details for these enhancements are found in the article, "CI Enhancements in 6.0," in chapter 10, "Technical Articles."
