Opening A File

Hey, I reposted this, because i feel i explained it badly

is there an easy way to get the
FIRST character in a line, do something with it
second character on the *SAME* line, do something with it
third, fourth .. ect going on to 50

then going to the
NEXT LINE
and doing the same thing.

but like, recording what position the CHARACTER is it
and what line the character is in
like:

abcdefghijklmnopqrstuv
123456789064826833

Character =A, Position = 1(first character), Line 1
do that with every charater in the FIRST line, then do it with the second line..

CAN YOU EXPLAIN IT MORE CLEARLY!!! OR AM I JUST 2 DUMB TO UNDERSTAND IT?...:) ANYWAY TRY SIMPLIFYING IT MORE.

you could try putting the line into a string
then use the left function to extract the first character of each line
