You can use local to make a variable local to a function. When a variable is made
local, it inherits the initial value and exported and read-only attributes from the
variable with the same name in the surrounding scope, if there is one. Otherwise,
the variable is initially unset.
qsh uses dynamic scoping, so that if you make the variable alpha local to function
foo, which then calls function bar, references to the variable alpha made inside bar
will refer to the variable declared inside foo, not to the global variable named alpha.
The special parameter - is the only special parameter that can be made local . By
making - local, any shell options that are changed with set inside the function are
restored to their original values when the function returns.
None.

You can use readonlyto set the read-only attribute for the variable(s) specified by
name. A variable with the read-only attribute cannot have its value changed by a
subsequent assignment and cannot be unset.
Note that qsh can change the value of a variable with the read-only attribute. For
example, if PWD has the read-only attribute, it’s value will be changed when you
change the current working directory.
