/* Template for writing user programs in the Pro/ENGINEER environment  */

/* the following definition and include file are necessary */
#define   USRMAIN
#include  "spgusrgl.h"

/* This include file establishes useful variables for user needs. Those are:

1. D[i] refers to dimensions you see on the screen. 'i' is the index of a
   dimension you see on the screen.

   So, D[0] has a value corresponding to "d0" on the screen (or "sd0" if you
   are in SKETCHER mode). D[4] corresponds to "d4" (or "sd4") on the screen, etc.

2. DIM_NUM  Total number of dimensions on the screen.

3. DIM_SIGN_MODE - this is an integer.
   User program can assign it values: DIM_SIGN_MODE_TRUE and 
   DIM_SIGN_MODE_RELATIVE.

   This variable controls the way how negative values are assigned to dimensions
   Having it = DIM_SIGN_MODE_TRUE establishes "true value assignment",
   DIM_SIGN_MODE_RELATIVE - "relative value assignment".

   For example, if old value of d1 = -5.0 and usrmain() contains

   DIM_SIGN_MODE = DIM_SIGN_MODE_TRUE;
   D[1] = -10.0;

   then d1 will be assigned new value = -10.0 ( true value assignment ).
   If user program contains
   
   DIM_SIGN_MODE = DIM_SIGN_MODE_RELATIVE;
   D[1] = -10.0;
   
   d1 will be assigned new value = +10.0 ( relative value assignment ).
   Relative value mode determines sign of the result as a multiplication
   of previous sign by the sign of incoming value.

   DIM_SIGN_MODE has default value = DIM_SIGN_MODE_RELATIVE.
   User can change DIM_SIGN_MODE several times in a program,
   but only the last value will be used.

   Example - establish the relation 1/10 between the first two dimensions:
