<@VARPARAM NAME=varname [DATATYPE=datatype] [SCOPE=scope]>
The <@VARPARAM> meta tag is used to explicitly pass a value in the <@CALLMETHOD> meta tag. This meta tag instructs Tango Server to generate the appropriate binding call.
The NAME attribute is the name of a Tango variable to be used for parameter binding. The SCOPE attribute is an optional attribute defining the scope of the variable named in the NAME attribute.
The DATATYPE attribute is used only for COM Variants, and accepts the name of a COM data type to use (this is equivalent to using the parameter Type drop-down menu in the Call Method action). DATATYPE is ignored for non-Variant parameters.
For examples of the use of <@VARPARAM> within the <@CALLMETHOD> meta tag, see <@CALLMETHOD>.
