Basic IDE problem: If we place cursor on variable with underscores in name and click "Enable Watch (F7)" for adding variable to Watch window, it performs incorrectly. Adds only part of name.
Problem seen also if double click on such variable name in program's text. Only part of name selected.
Steps to reproduce:
0. Start any LO module, for example, Writer
1. Press Alt-F11, in dialog "LibreOffice Basic Macros" press "New" and then "Ok"
2. In Basic IDE enter something like this:
3. Place cursor on variable name and press "Enable Watch (F7)"
Expected: added variable with correct name to window "Watch"
Actually: added only part of name, for example First instead of First_Result
reproduced in 3.4.2 on Windows XP 32 bit and in 3.6.3 on RFR 17 64 bit
Workaround: select correct name of variable manually and press F7
Confirmed in build from 12/20 master. This issue is a more general IDE interface issue of selecting whole identifiers (on dbl click, on add to watch, ???).
Selection in BASIC IDE should extend the selection from cursor to cover an entire identifier that contains any legal character. This should include extending the selection to whole keywords that contain other chars invalid for identifiers (like the $ at the end of CHR$()). I can confirm that is a long-standing issue. Moved to NEW.

The selection in the Basic IDE is done with a generic method in
TextView::MouseButtonDown(const MouseEvent & rMouseEvent) (vcl/source/edit/textview.cxx) using the i18n::XBreakIterator implementation.
For Basic there should be the possibility to call a custom 'select word' method.
WIN 10 32&64bit LO CALC 184.108.40.206 BASIC IN IDE: When stepping thru a program, hovering over variablenames containing an internal underscore: the values do not popup. Works fine for variablenames without underscores.
Simple Test: Variables named A and B and A_B even tried [A_B] but hovering over A_B or [A_B] produces no popup except individually on the A or B within the A_B or [A_B] and they were the values of the singleletter variablenames.
Further on the program utilizes the value of the A_B variablename correctly
WIN 10 PRO 32&64 Bit Also tried A__B (double underscore) and [A B]
blank not underscore in variablename in Brackets. Both these fail in the same way.

Might be related to this bug: variable selection is not easy in the IDE when variables contain underscores. A triple click selects the whole line instead of selecting the identifier only.
Second, this is not consistent with Calc and Writer where a triple click actually selects "words" containing underscores.
Wanted behaviour: triple-clicking an identifier containing underscore(s) selects the identifier only.
Current behaviour: selects the whole line.
When your selection length is 0, Basic IDE tries to find what is the name of the identifier
2. it relies on BreakIterator for Word Break
3. BreakIterator uses data for "edit_word" (I'm not so sure)
4. So-called underscore,whose official name is U+005F LOW LINE and who is in "Punctuation, Connector [Pc]" Category is categorized into ExtendNumLet in UAX#29
5. WB13a and WB13b says this character breaks neither before and after alphabets.
While icu4c's official data has a section for WB13a/WB13b,
LibreOffice does not have such a section.
Can this be the cause?
ICU's break iterator does not consider underscores as word-breaking punctuation
