It is possible to construct functions with more than four parameters. This is done in several steps. Up to 62 parameters can be added to a function (allowing for up to 30 names and values to be set or read in a request). Commands associated with creating and sending requests in steps begin with +, so they do not overlap with actual VOX command names.
These commands are:
Arguments in the constructed functions must be placed in positions in accordance with the definitions for the VOX Server commands.
Replies to requests are preserved until the next +create command, or until any request not beginning with a + is used. It is permissible to use +getarg to read responses from commands that were not built with +create. Any request that does not begin with + uses the +create, +setarg and +getarg mechanism internally.
Note:
The + commands should not be used to construct requests that cannot accept a variable number of arguments.
