System default user ID

At system startup, systems support uses the DEFLUID system parameter to define a default user ID which is valid throughout the system (usually $TSOS). The nonprivileged software products available to all users (e.g. utility routines, editors, compilers, etc.) are cataloged under this user ID.

A user may access these files without specifying a user ID by placing “$.” or the $ character before the file name. If the file name is divided into partial names by periods, the string “$.” must be placed in front of the name. If no such division exists, it is sufficient to place the $ character in front of it.

This system default user ID is also significant for secondary read access (see section"Access via the system default user ID").

Example

Editor: $.EDT, $EDT
Compiler: $ASSEMB
Utility routines: $SORT, $PERCON, $DPAGE, $TSOSLNK, $LMS, $.ARCHIVE
