Re: Bizarre Error

[pand9613]

Jwe, 
Since you used the variable "a" in your testfile.dat and then run the code, a 
is reassigned to [1,2;3,4] and hence does not initiate a second running of the 
while loop. (since the value of "a" is the condition). Try a different variable 
name and let me know the results.

Also I just found that i did infact need to run the code from inside a while 
loop to get the error however once the error had occurred once it would occur 
again whether the lines of code were run inside the while loop or not. This 
continued until i restarted octave.
