formatting a text file for display by other applications

[Stu]

I'm trying to write a flat text file to be displayed in 3D by GNUplot, but I can't seem to get the various pieces I need to do this to work. I start with three arrays of integers, x, y, and z, and then format them into a columnar arrangement with

⍕⍉(3,×/⍴M)⍴x,y,z

The result displays correctly and has ⎕DR 80. PutText doesn't like this even though the documentation says it requires 8-bit data. If I could get PutText to work, I might still have a problem because GNUplot expects Unicode text files. I need some advice on how to solve this.

Just a guess but whatever PutText is it probably doesn't like 2d data. Try catenating a lineend after the array and ravelling the result.

PutText is in the Files namespace that comes with the current Dyalog distribution. When I display my 3-column array of coordinates on the screen, it looks like the newline character is already there because I get three correct columns.

      ⍕⍉(3,×/⍴M)⍴x,y,z

produces a 2d character array with blanks between the data columns. If you assign it to a, then perhaps

      (,a,⎕ucs 13)

might be an acceptable argument to PutText. I don't know. Maybe it's objecting to something else.
