  I have a problem with neqn, and since DEC software support can't help,
  maybe someone has solved the problem already, or can at least send me a
  copy of a tabXXXX.c file that definitely works for the problem.
  The problem:
	I follow the directions of BSD manuals, and enter control codes
	into a file containing a structure (took the default, and put my
	codes in) appropriate for terminal definition file for nroff -TXXXX .
	I can get everything to work for DEC LN03 laser printer (as well
	as for LA100f w/ greek/math character rom), except the square root
	'macro?'. If I print the same escape sequence (via C program), it
	creates a beautiful square root. Assuming strings in parens represent
	one octal code, or one character, I use a line similar to:
	"/201{char to shift font}{char to go up half line}{bottom of sqr root}
	{char to go back up half line}|{char to go up another half line}{the
	top char of sqr root}{char to go back down half line}{char to go back
	to default font}",
	
	For the LA100f output goes through a filter, for LN03, it goes right to 
	the printer. Obviously neqn/nroff must split the sqr root symbols up 
	into several categories. Characters appearing once before a repeatable 
	character, the repeatable character, and characters appearing once after
	the repeatable character. There is obviously some format neqn/nroff is 
	looking for, assuming it ever worked. Can anyone help? I have older
	source for nroff, but couldn't find mention of sqrt, or similar. The
	root en 'macro?' has a similar problem, but only two characters.

  Is there a readable guide for adb, and can it be used gainfully by
  mere mortals ? :-)
