OMI- Global Reference 1995 Version of ANSI (Equivalent to Current ISO Version) of Standard

5.3.3 Global reference

4.1 describes the environment, the global variable name (gvn) and the lock argument (nref) that appear in many OMI messages, where they have the following form, called a global reference.

A global reference shall be a long string <LS>. Its fields shall be strings containing the environment, global name and subscripts.

Note – The protocol does not support MUMPS naked references. The agent shall send full references for all operations.

The fields of the global reference and their sequence shall be:

1. Environment: <LS> denotes the server's environment for this global reference. See 4.1 and 4.7.
2. Name: <SS> The name shall include a leading caret as shown in 4.1.
3. Subscript(s): <SS> 0 or more subscripts. Each shall be a short string, thus limited to 255 characters. Numeric subscripts shall appear as ASCII characters, not as binary numbers or other internal representation.

Note – The number of subscripts is implied by the length of the entire global reference, a long string <LS>.
