UnitData
Gets the numerical data of a processing unit.
Format
UnitData(<unitNo>, <dataNo>)
UnitData(<unitNo>, <dataIdent>)
Parameter
Return value
Returns processing unit data as integer or double precision real values.
If non-numerical data is gotten, the data is converted to numerical values and returned.
Description
Gets numerical data of the external reference data number specified in the <dataNo> parameter, in the
processing unit specified in the <unitNo> parameter. The data can also be gotten by specifying the
<dataIdent> parameter instead of the <dataNo> parameter.
To get data other than numerical data, use the UnitData$ function or the GetUnitData function.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a non-existent number, numerical value, or combination of data types or values is specified for a parameter,
an "Illegal function call" error will occur.
If a value is assigned to the return value variable or the variable is not used in an expression, a "Syntax error"
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
Gets the value of the measurement X coordinate of the search processing unit of Processing Unit number 5.
The measurement X coordinate is external reference data number 6 and external reference data
identification name "X".
Parameter
name
Data type
Description
<unitNo>
Integer type
Processing unit number (0 to (the number of registered processing units in the current
scene minus one))
<dataNo>
Integer type
External reference data of the processing unit data to get (reference:
X

<dataIdent>
Character
string type
Data identification name of processing unit data to be gotten.
SEARCH# = UnitData(5, 6)
Rem The same result can be gotten by specifying "X" instead of 6.
SEARCH# = UnitData(5, "X")
