If I do a search for file_save, it shows up as C-script: file_save. Nothing is remarked about it being a c-script function only (nor does it come up in the outdated syntax list).
but if I look through the index, it shows up normally. Without the C-script remark.
This has actually gotten me really confused, and needed explanation from a forum member (EvilSOB) before I noticed it was actually a manual mistake.

regards,

In the manual i also miss the tex_light u can only find it in aum32

I think this is nothing at all related to my issue... Please make your own thread for another Manual mistake

The "C-Script" is displayed with most commands, not only file_save. I think its some relict and can be ignored.
