This list gives a brief description of the most useful functions to
manipulate text in the Visual Basic language of Microsoft Access. Many of these functions have
an alternate form which returns a string
rather than a variant - for example Left() and
Left$(). Access Help gives
more details and will describe exactly how these functions operate in your
version of Access.
Note that these VBA functions are always followed by a pair of brackets even
if - like Date() - there's nothing in between them. The Access editor
will sometimes remove these brackets but by entering them you are telling
Access that you are attempting to use a function.
