Trying to update a plugin to run in FH7 and would welcome some advice.

The plugin used the "table.maxn" function and is now generating an error as that function has been deprecated.

The plugin looked through my FH database seeking a particular fact and if found it copied the 4 elements of the fact to a table.

I used the table.maxn function to determine the table size i.e. if the loop search failed to find any facts then the result would be just the headings I placed in the table at the beginning of the loop.

The plugin runs OK with these few lines commented out and it only use was to report (in the exported text file) if no facts were found.
So, my question is there a alternative and simple way to replicate the table.maxn function?

The help file for writing plugins has some advice as does Writing and Maintaining Plugins Compatible with Versions 5, 6 & 7.

That works perfectly.

Thank you

Since you are using table.insert(tblFile,...) the table index values will start at [1] and be consecutive up to [4].
The size of such tables can be obtained using the length operator #, i.e. if #tblFile < 4 then
That works in FH v5, v6 & v7 with both versions of Lua.

Interesting. I will explore that.

Thanks
