join columns

[Phil Davis]

If pData is a CR-delimited list where each line contains tab-delimited 
items, why not use 'split by column'?

-- example: switch positions of columns 2 and 4

    split pData by column
    put pData[4] into tTemp2
    put pData[2] into pData[4]
    put tTemp2 into pData[2]


-- then put it back together as a list:

    combine pData by column

That should do it.
