DCL:GRPH2:U[XYZ]PACK: Cartesian Coordinate Axis Routines
This is the routine group that performs the actual drawing in the subroutine packages UXPACK/UYPACK/UZPACK. The routines are written using the Basic Routines, and the user rarely calls them directly. These are used to create upper-level applications (ULA).
The argument cside common in the descriptions below is a parameter which specifies the position to draw the axis component, and 'B', 'T', and 'U' can be specified for the x axis, and 'L', 'R', and 'U' for the y axis. (For details, see Section 3.2.) Also, the argument islct is a parameter which specifies the attributes of the axis components, and takes the values 0, 1, or 2. (For details, see Section 3.4.)
