Reserved Variables

Special variables reserved by Murex

In Murex, there are five different classes of variables:

1. Local variables (scope limited to a function et al)
2. Module variables (scoped to a module)
3. Global variables (available to every function within Murex but not shared with processes outside of the Murex’s runtime)
4. Environmental variables (available to every function and process – internal and external to Murex)
5. Reserved variables

Reserved variables are data that are available to any code running within Murex and exposed as a variable.

Reserved variables are called reserved because they are read only.

Reserved variables are often also dynamic, returning different values based on contextual circumstances.

» set SELF="foobar"
Error in `set` (0,1): cannot set a reserved variable: SELF
