VariantPut (Write VARIANT tag value)
You can use the "Write VARIANT tag value" instruction to write the value of the tag at the

The DST parameter has the VARIANT data type. Any data type except for VARIANT can be
specified at the SRC parameter.
The data type of the tag at the SRC parameter must match the data type to which the
VARIANT points.
