Going through every token/word on every line

Hi,

I am after a method of
1). Going through every line in the document
2). Going through every word/token in the document

as I am writing a wizard that looks for variables that start with a number

the code would look something like

For i as int16 = 0 to rows.count - 1
for j as int16 = 0 to row(i).words.count - 1
// Do code with row(i).words.item(J)
next j
next


Would someone show me how this is done, thank you!
