GetSceneData
Gets data related to the scene control macro.
Format
GetSceneData<dataldent>,<data>
Parameter
Return value
None.
Description
Gets the data identified by the identification name specified in the <dataIdent> parameter.
In the <data> parameter, specify the variable that will store the gotten data.
If the data type of the data to be gotten is different from the data type of the variable specified in the <data>
parameter, the gotten data will be converted to the data type of the <data> parameter.
In the <dataIdent> parameter, specify the variable name to be used in the scene control macro program.
If an identification name that does not exist is specified as the parameter, an "Illegal function call" error will
occur.
Even if a combination of different data types is specified as parameters, an error will not occur.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
Usage Cautions
• None.
Example
Uses the unit macro to get the integer variables "SearchResult0&" and "SEARCHRESULT1&" defined in the
scene control macro
