to something that was not a function (for example, a variable).
Action: Make sure that name is a function and spelled correctly.
Message: name: parameter null or not set
Cause: You specified a ${name?} construct where name was not set and no message
followed the ?.
Action: Set name and specify a message after the ?.
Message: name: readonly variable
Cause: You attempted to change or remove the variable name which was marked as
read-only.
Action: Do not attempt to change or remove a read-only variable.
Message: "name" is not an identifier
Cause: You attempted to use an non-alphanumeric name as an identifier.

priate permissions.

Cause: You attempted to send output to or receive input from a co-process when there
was no active co-process.

co-processes.
Message: no command matches "string"
Cause: You attempted to use fc to edit a command beginning with a particular string,
but there was no such command in the history file.
Action: Use the fc command to browse through the history file to ensure that string is
entered correctly.

Cause: The
POSIX.2a wordexp() function called the shell to expand a string that con-
tained command substitution, such as $(cmd) or f(CW`cmd`.

expanded does not contain any command substitutions.
