Hi Alex,

very good, thank you very much. I have added it as:

This revision adds the following:

1.switch from ⎕av to ⎕ucs

2. works for >2 columns

3. Left argument is the record separator. I didn't make it optional because I like the visual aid in the code rather than having to remember an arbitrary default case. 

4. On Louis' suggestion, it now supports "Quoted Data", incase your data item contains a comma

5. Against Louis' suggestion, I never count the number of delimiters and add 1. :)

Please see attached

Hi Alex,

thanks for offering this. I would change a few things to make that code even more useful:

- make the separator an (ideally optional) left argument of ReadTableData.
  Many data files are written in CSV (comma separated values) format which uses comma instead of space,

- use ⎕UCS instead of ⎕AV to make the code more portable between different APL interpreters,

- and maybe make it work for > 2 columns (by guessing the number of columns from the first line in the file).

Hi Bug-apl,

I am soliciting feedback (as per the process) of the attached APL code that will take a file  that has a layout of two columns (space separator) and return a matrix.
