Hi Robert Hi All,
  I am not new to Euphoria but I have not used Euphoria in a very long 
time.  Anyway I am back with Euphoria again and I can't remember some 
things about it.  I clipped this from the documentation but I am not 
understanding something here and I know this may seem simple but here it 
goes anyway.  In Example 2 below what variable type is "i" in the line 
"for i = 1 to length(x) do".  I tried this same simple for loop and 
declared i as an integer but when I run the program it says that I am 
trying to redefine that variable.  If anyone could give me a kick start 
back into Eu I would greatly appreciate it.

sequence
Syntax: i = sequence(x)  
Description: Return 1 if x is a sequence else return 0.  
Comments: This serves to define the sequence type. You can also call it 
like an ordinary function to determine if an object is a sequence.  
Example 1:  
 sequence s
s = {1,2,3}


 
Example 2:  
 if sequence(x) then
    sum = 0
    for i = 1 to length(x) do
        sum = sum + x[i]
    end for
else
    -- x must be an atom
    sum = x
end if


 


See ya on the Net
