/* Sc parse routine
*
* usage psc options
* options:
* -L Left justify strings. Default is right justify.
* -r Assemble data into rows first, not columns.
* -R n Increment by n between rows
* -C n Increment by n between columns
* -n n Length of the row (column) should be n.
* -s v Top left location in the spreadsheet should be v; eg, k5
* -d c Use c as the delimiter between the fields.
* -k Keep all delimiters - Default is strip multiple delimiters to 1.
* -f suppress 'format' lines in output
* -S Use strings vs numbers for numbers
* -P Use numbers only when there is no [-+eE] (plain numbers only)
*
* Author: Robert Bond
* Adjustments: Jeff Buhrt, Eric Putz and Chuck Martin
