Fill an array from an (unreferenced) list?

[Peter Quain]

If you want flexibility and to avoid finicky typing, perhaps you could:
- type the words in text documents, 1 word to a line. you have 
seperate arrays for each stimulus type ... and you need to type the 
stim sometime
- open the text documents to read, 1 at a time
- run a loop, reading each line of the document and saving it as the 
string in each cell of your array

Something like this would allow lists of differing length to be read in.
...
' for 0 option base
Dim YourArray() As String
Dim s$ As String
Dim LineCount As Integer
Dim n As Integer

' Find out the number of lines
Open "YOURFILE.txt" For Input As #1
LineCount = -1
Do While Not EOF(1)
LineCount = LineCount + 1
Input #1, s$
Loop
Close #1

' make the array the size of the document...
ReDim YourArray(LineCount)

' Read in the stimuli
Open "YOURFILE.txt" For Input As #1
For n = 0 To LineCount
Input #1, YourArray(n)
Next n
Close #1
