5: .sp
6: .PP
7: MDS is the symbolic format for the Kollmorgen Pck Division channel router.
8: This is an abbreviated description of the format.
9: .sp
10: .I Introduction
11: .PP
12: All MDS data is made up of integers, symbols and keywords. All coordinates
13: are expressed in mils, i.e., 1/1000 of an inch (just like fizz!). Coordinates
14: can be negative or positive and are denoted by matching parentheses of
15: the form (X Y). Symbols require quotes around them if
16: not made up of numbers, letters, $ or a _.
17: .sp
18: .I Data types
19: .PP
