Call
Executes the registered user-defined function.
Format
Call <subroutineIdent>[; | ,
<argument>...]
Parameter
Return value
None.
Description
Calls a user-defined function with the specified identification name by the <subroutineIdent> parameter and
executes the function. If the user-defined function has arguments, the specified data by the <argument>
parameter is passed to the user-defined function. In the <argument> parameter, specify an argument
according to the user-defined function definition.
Register a user-defined function with the SetUserSubroutine function before executing this function.
How user-defined functions work depends on the defined processes in external DLL files.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a user-defined function that is not registered is specified for a parameter, an "Illegal function call" error will
occur.
If a character string longer than 255 characters is specified for a character string parameter, a "String too
long" error will occur.
In case an error is returned as a result of the user-defined function execution, this Call function will return one
of the following errors.
• Syntax error
• Illegal function call
• Out of memory
• Type missmatch
If this macro function calls a user-defined function that has not been programmed with a supported interface,
an error occurs during the user-defined function processing.
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.
