4D does not provide its own spell checker or dictionary. Therefore, if you are using 4D Write and wish to use a spell check tool, you will have to use a third party product. Some spell checkers that are compatible with 4D Write are SpellsWell, Spell Catcher and the Microsoft Word spelling checker.
Note: SpellsWell is no longer being sold.
You can get Spell Catcher at https://www.spellcatcher.com/.
From within 4D Write, once the spelling option has been selected from the Tools menu, you will be asked to select both a spell checker and a dictionary. If you plan on using Microsoft Word's spell checker, you will have to locate the Microsoft dictionary.
On a Macintosh the MS Word spell checker and dictionaries are located in:
Macintosh HD:Applications:Microsoft Office 98:Shared Applications:Proofing Tools
Under Windows the path to the MS Word spell check is:
C:\Program Files\Common Files\Microsoft Shared\Proof\Mssp232.dll
and the path to the MS Word English dictionary is:
C:\Program Files\Common Files\Microsoft Shared\Proof\Mssp2_en.lex
