Thanks Ted.
This is helpful. Currently I am using two column tables for creating
diagrams explaining command syntax. The number of columns and formatting
remain the same but row-count is the changing variable.
Are there resources you would suggest that draw together the pieces
necessary for writing groff macros? I've read Provins, Lesk the info
pages and am looking through the tmac files currently. The tmac files
hold promise but was hoping for a more basic resource that explains some
of the issues with newlines, escapes and macros or ds calls within
macros, building strings ...etc.
Thanks again ~ your example illuminates some things. Will play around
with it.
