Concatenating large number of files

[#1]

Hi Guys,

I am trying to concatenate several files in a folder as below:

[#2]

That sounds great, unfortunately I am using JMP13

[#3]

There is a JSL error, I think, here

If( Ends With( y[i], "csv" ), 
 0 // need something here, a zero is good enough
, 
  Remove From( y, i ) 
) 

the two adjacent commas need something between them. A 0 is a very tiny expression that evaluates to 0 and does nothing else. (Or switch the logic around with !EndsWith(...) where ! means NOT.)
