UnitData$
Gets the character string data of the specified processing unit.
Format
UnitData$(<unitNo>, <dataNo>)
UnitData$(<unitNo>, <dataIdent>)
Parameter
Return value
Returns the character string data of the processing unit as a string type value.
If non character string data is gotten, the data is converted to a character string and returned.
Description
Gets the data of the external reference data number specified in the <dataNo> parameter, held by 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 character string 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 decode character string of the 2D code processing unit of Processing Unit number 5. The decode
character string is external reference data number 7 and external reference data identification name
"decodeCharStr".
Parameter
name
Data type Description
<unitNo> Integer type
Processing unit number (0 to (the number of registered processing units in the current

<dataIdent>
Character
string type
Data identification name of processing unit data to be gotten.
DECODECHAR$ = UnitData$(5, 7)
Rem The same result can be gotten by specifying "decodeCharStr" instead of 7.
DECODECHAR$ = UnitData$(5, "decodeCharStr")
