In v6 of FMP I was able to use: external(Web-toHTML; "field") or something very similar to create a text calculation field that would convert another text field to HTML text on the fly (converting things like ™ into ® or whatever the ascii code is).

I believe this was because the web conversion for FMP was all external. Now that FMP 7 is more advanced and has more web publishing built-in (I think), I can't find this external command any more. Is there a way to do a similar calculation in v7?

Any "external" function comes from a plugin. Not all FM6 plugins are compatible with 7/8, so find that plugin you were using and check their website if they have an update.

FM has no native functions to do what you want. But you can certainly write a calculation with a bunch of substitutes if you want

FM's enhanced web publishing does not extend to functions inside FM.

Thanks Wim - however in v6 the "external" command used the FMP web companion (part of the installation of FMP v6). So that set of features/functions is no longer part of the install (unless I missed it someplace). That's what I'm trying to establish - was this part of the standard install for v7, or is it a function no longer available in v7 and how can I replicate what used to be available.

Thanks
