Reserved Variables

Special variables reserved by Murex

In Murex, there are different classes of variables:

• Murex variables, of varying scope:
  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)
• Environmental variables (available to every function and process – internal and external to Murex)
• Reserved variables

Reserved variables are Murex variables which contain read-only runtime data and thus made available via Murex’s runtime rather than assigned by any running Murex code.

Reserved variables are called reserved because they are read only.

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