Hi Alan,
There are the antique Basic file I/O statements (Open, Line Input, etc)
or the newer FileSystemObject object (in the Microsoft Scripting Runtime
library) which has a TextStream object with ReadLine and similar
methods.
As well as the classic string handling functions (Instr(), Mid() etc)
there's also a Split() function which parses a simple delimited line
into an array. The VBScript Regular Expression object is fairly powerful
(the regex syntax is AFAIK the same as Perl 5.0 or thereabouts) and
easily used in VB or VBA code.
