ci.pub.sys). An MPE file may have an optional eight-character lockword which is separated from the filename by a slash (e.g.,
Names in the MPE Name Space may only contain upper case letters and numerals, must start with a letter, and are 1 to 8 characters long. Unlike in UNIX, the names are not case sensitive and may not contain characters such as the underscore (_), dot (.) and dash (-). This applies to filenames, group names, account names and lockwords. An MPE Name Space file always resides in an MPE group of an MPE account. On a POSIX version of MPE, the accounts are always subdirectories of the root directory, with groups as subdirectories of each account.
Here are some files in the MPE Name Space and their equivalent names in the Hierarchical File System:
DAYS.COBSRC.DEV /DEV/COBSRC/DAYS weeks.cobsrc.dev /DEV/COBSRC/WEEKS Cob85xl.Pub.Sys /SYS/PUB/COB85XL
By default, in MPE commands a filename is assumed to be
in the MPE Name Space. Therefore,
looks for "ABC", not "abc". If you want to refer to a file
in the HFS, put a Dot (.) or Slash (/) in front of it.
:purge ./abc looks for "abc" in
the Current Working Directory.
