EGL0201E `The function_name String function failed with error code 12.`

Explanation

The length must be greater than zero.

User Response

Do as follows:

Change the program logic to ensure that the length arguments passed to the function have values that are greater than zero; or
Call the function in a try statement, or set vgVar.handlesysLibraryErrors to 1 before calling the function, so that the program can handle the error.
