    My first thought was to try to use the %+ operator.. the problem is
that the vt100 needs the col/row code in printf %d format, not %c...

(excerpt from our man page..)

     The % encodings have the following	meanings:
 
          %%   output `%'
          %d   output value as in printf %d
          %2   output value as in printf %2d
          %3   output value as in printf %3d
          %.   output value as in printf %c
          %+x  add x to value, then do %.
          %>xy if value > x then add y, no output
          %r   reverse order of two parameters, no output
          %i   increment by one, no output
          %n   exclusive-or all parameters with 0140 (Datamedia 2500)
          %B   BCD (16*(value/10)) + (value%10), no output
          %D   Reverse coding (value - 2*(value%16)), no output (Delta Data)

   The %+x would output a character, rather than a string representing the
row or col.  Thanks anyway...
