Fusion expression does not work when using a long string

Question

I'm trying to use a long string in a Fusion expression.
I am using a string created with a text editor and pasting it with an expression, but if the string becomes long enough, it will not work. Please tell me the reason.

Answer

There is a limit to the strings that can be used in expressions, up to 1022 bytes.
If the length is longer than that, please devise measures such as using an external file with a frame render script or dofile.
