I found that adding a long text string as an input parameter description for a UDF seems to prevent the UDF from compiling properly. The string causing the problem was 272 characters long. Reducing it to about 160 characters solved the problem.
Is there a specific limit on the total length of the docstring, and/or the length of each line, and if so is there any way to get around that?
Also the manual refers to linking to a help file. What format should that file be in?
