The given names are marked readonly and these names cannot be changed by subsequent assignment.
On this man page, ksh(1) commands that are preceded by one or two ** (asterisks) are treated specially in the following ways:
Variable assignment lists preceding the command remain in effect when the command completes.
I/O redirections are processed after variable assignments.
Errors cause a script that contains them to abort.
Words, following a command preceded by ** that are in the format of a variable assignment, are expanded with the same rules as a variable assignment. This means that tilde substitution is performed after the = sign and word splitting and file name generation are not performed.
