Hey there felice...

The easiest way would be to use the "textfile to table" function. So if your textfile has 4 lines of text...say:

www
xxx
yyy
zzz

Then using the textfile to table function (and calling the table MyTable) would create a table called MyTable which would look something like this to the computer:

{www,xxx,yyy,zzz}

You could then call upon any of that table's elements by requesting the info from a specific slot. In this case www=1, xxx=2, yyy=3 and zzz=4. You could convert a table's element into a variable (say..."MyVariable") using the following code:

MyVariable = MyTable[1]

This would mean that wherever you use the variable "MyVariable", it would have the value of "www" (or whatever is in position 1 in the table you created ealier). If you typed "MyVariable = MyTable[3]", then "MyVariable" would have the value of "yyy" (or whatever was in position 3 in the table you created), etc.

You can then use the String Left funtion to create a string from the Left-most character of the new String called "MyVariable" calling it...say..."MyString". Now if MyVariable had a value of "www", then MyString has a value of "w".

Now use the Add To Listbox function and insert MyString to the index of your choice (0 being the first index and -1 being the last).

These are listed in the help and tutorial section of AMS, but I know that it's sometimes easier to have someone walk you through it. Play around a bit with these directions and modify as you see fit. Have fun! Let me know if this isn't what you were looking for...
