Reading Data from a Rich Text Box

[Azz00]

Hello again
Say i had a Rich text Box with this in it.

float 0.000000, 0.000000, 0.000000 ;vertex 0
float 0.000000, 0.000000, 0.000000 ;vertex 1
float 0.000000, 0.000000, 0.000000 ;vertex 2
float 0.000000, 0.000000, 0.000000 ;vertex 3
float 0.000000, 0.000000, 0.000000 ;vertex 4
float 0.000000, 0.000000, 0.000000 ;vertex 5
float 0.000000, 0.000000, 0.000000 ;vertex 6
float 0.000000, 0.000000, 0.000000 ;vertex 7

How could i make my app Read 4 lines at a time

and get thoes 0.00000 Values and store them as say
A
B
C
D
E
F
G
H
I
J
K
L

? then my app would do some calculations with thoes values ?

how can i do that ?

is the length of the 0.00000 always the same?

how many lines will be in the textbox?

will it go above 9? (so that it has 10 on the end..therefore increasing the number of chars)
