When a BS2000 user ID is created, the POSIX user attributes are initialized with the default values of the specified pubset. The operand value *BY-POSIX-USER-DEFAULTS always refers to the default values of the specified pubset.
The POSIX user attributes are automatically created during first startup or version changeover; they are initialized with predefined values:
| USER-NUMBER | = | 100 |
| GROUP-NUMBER | = | 1 |
| COMMENT | = | *NONE |
| DIRECTORY | = | *ROOT |
| PROGRAM | = | *SHELL |
With the exception of TSOS and SYSROOT, all BS2000 user IDs are first assigned the default user number and the default group number.
During first startup, the TSOS and SYSROOT system IDs are created with the predefined user number 0 and group number 0. The user number cannot be modified, but there are no restrictions for the group number.
The defaults for the user attributes can be changed with the command "MODIFY-POSIX-USER-DEFAULTS". You can use the command "SHOW-POSIX-USER-DEFAULTS" to view the attributes.
