A convoluted way using a plot statement is to use plot 'file' every 1:1:line_no:block_no:line_no:block_no using ($col_no = time) for example, which allows a block, line, and column number to be specified and assigned to the variable time. However, I'd like to be able to do this without invoking a plot statement. Any suggestions?
