A '''Intrinsic Special Variable''' is something you type into a MUMPS program, which fits into the syntax in the places that a variable normally would be used.

It is named a '''special variable''' because rather than just having the value that is given to it by the current running MUMPS program, it has a value that is changing based on some internal ("intrinsic") logic that is provided by the MUMPS language implementation.

Intrinsic special variables have a syntax that is similar to that of functions in the MUMPS language. Their names start with the dollar sign character "$" and are some alphabetic letters, without any difference in name based on whether they are upper case letters or lower case letters.

Examples of Intrinsic Special Variables are:
