Opened in word:
mintab-1.doc has a para with tab stop at 0x237 twips and indent of
0x237, a tab at the start of the para jumps to the next tabstop
mintab-2.doc has a para with tab stop at 0x237 twips and indent of
0x236, a tab at the start of the para jumps to the next tabstop
mintab-3.doc has a para with tab stop at 0x237 twips and indent of
0x235, a tab at the start of the para moves to the 0x237 tab stop.

So it looks like a min tab distance of >= 2 twips

A real world example

The final attachment opened in word places the first tab so that we
move to 2.54cm, while in writer we jump to 3.81cm. Presumably because
of a different minimum tab value.

(but the mintab-2 example which jumps to 5cm in word stays at 1cm in
writer, which confuses me, unless there are different rules for
leading paragraph indent in writer ?)

cmc->fme: As discussed in the past we have to try and do something in
layout to emulate the tab stop positioning as shown in these examples.

I thought it was simply a minimum tab distance setting we needed to
change, but attachment two (mintab-2.doc) confuses me.

FME->CMC: Strangely, this behavior depends on the formatting device.
If we use the virtual formatting device in word, it looks like this:

mintab-1.doc has a para with tab stop at 0x237 twips and indent of
0x237, a tab at the start of the para jumps to the next tabstop

mintab-2.doc has a para with tab stop at 0x237 twips and indent of
0x236, a tab at the start of the para moves to the 0x237 tab stop.

mintab-3.doc has a para with tab stop at 0x237 twips and indent of
0x235, a tab at the start of the para moves to the 0x237 tab stop.

So it looks like a min tab distance of >= 1 twips if the formatting
device is the virtual device.

Our code uses a minimum width of 50 twips, but only for the default
tab stop positions, not for user defined tab stops.

Another real world example (Word document).

For interests sake, what sort of rules did we end up with for
compatability ?

FME->CMC: It's one twip minimum for user defined and default tab
stops, no matter if you use the printer or the virtual device for
formatting. Have a look at the spec on specs.openoffice.org.

Fixed in cws tabstops.

SBA: Verified in CWS tabstops.

SBA: Set to verified.
