Description

This method is used to describe an APL variable that is to be exported as a property of an ActiveXControl or OLEServer object.

The argument to SetVarInfo is a 2 or 3-element array as follows:

Variable info is either a simple character vector that specifies the COM data type of the variable, or a 2-element vector of character vectors whose first element specifies a help string and whose second element specifies the COM data type.

Help ID is an optional integer value that identifies the help context id within the help file associated with the HelpFile property of the ActiveXControl object. The value ¯1 means that no help is provided. APL stores this information in the registry from where it may be retrieved by the host application.
