Filename Mapping

All filenames used by CLE/P® are additionally mapped based on the rules below:

The tilde character (~) is replaced with the string <HOME>
DD names on mainframes must be prefixed with "DD:"
Data set names on mainframes are always fully qualified
Path names on mainframes must contain at least one slash (/)
Data set names on USS must start with //
- Fully qualified names with HLQ must be enclosed in apostrophes (//'')
- If apostrophes are not used the SYSUID is prefixed as HLQ
Normal file names on other platforms could be relative

If a requested environment variable is not defined, the replacement is done with the empty string. This can result in unexpected behavior.

To use a "<" or "~" as a part of a filename the character must be specified twice.

Beside this rules the replacement technologies of your shell can be used, but on some platforms $HOME, $USER or something similar might not be available, for such cases the possibilities above are implemented.

This file name mapping is provided by the library CLEPUTL and should also be used for file names managed by the commands supported with this program.
