Has anyone written a filter to convert human-readable board positions into input for the chess macros which came with 4bsd? (The documentation says that they're from Stanford, and I think you can also get them from Imagen and elsewhere.) It would take a board that looked like rnbqkbnr pppppppp ........ ........ ........ ........ PPPPPPPP RNBQKBNR And transform it into HTTTTTTTTX VrmblkansF VopopopopF V0Z0Z0Z0ZF VZ0Z0Z0Z0F V0Z0Z0Z0ZF VZ0Z0Z0Z0F VPOPOPOPOF VSNAQJBMRF WUUUUUUUUG The filter would work like tbl, eqn, pic, etc., fiddling with data between .CS and .CE or something. If no one out there has one, I suppose I might write it on some rainy day soon. Also, I have this font on an Imagen 8/300. What are the settings for spacing (with .cs and .vs) which yield the prettiest boards? (I have been using .ps 14, and .cs <point-size*2> doesn't work as nicely as it does in the Berkeley font catalog. Andy Tannenbaum Masscomp Westford, MA (617) 692-6200 x274

I decided after posting the message which this one follows that I
should write the filter I requested, for a program which takes human
readable chess board listings as input, and puts out troff chess font
output.
