Yep, that was what I was after.
The file consisted of 134,069 entries like
PD 456,78
in a HPGL plot file. So culling the starting and ending lines, the :,$
s/,/ / to replace the comma by a space and running ScoTt awk line
produced what I needed; the input to the IP paramters (bottom left and
top right of the plot area.
This is alll from trying to fix programs mentioned in the postscript to
HPG converter I am seeking.
Umm, with 134,069+ lines, sort was not an option.
Thanks all.
