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,

I would also add Tab Delimited, a very common format

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

May I suggest counting the number of delimiters + 1 in the line, as the number of columns?

Also, some programs produced “Quoted Data” in CSV files, to get around the fact that data may contain commas. Like this:

“Item 1”,”Item 2 has a , in it”,”Item 3”

A bit tougher to parse…

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.
