.PIE SET 3D DEPTH

This subroutine sets the sector 3D Depth for all pie sectors, a range of pie sectors, an individual pie sector, or the current pie sector.

Usage:

      PASS         <3d_depth>                 FIELD            SHARE? N
      PASS         <beg_sector_no>            FIELD            SHARE? N
      PASS         <end_sector_no>            FIELD            SHARE? N
      GOSUB    0CD .PIE SET SECT 3D DEPTH
      *        Check for error
      IF       0CD .PIE SET SECT 3D DEPTH     NE

Description:

This subroutine allows you to set the Sector 3D Depth for all pie sectors, a range of pie sectors, an individual pie sector, or the current pie sector.

If <3d_depth> is not received or is blank, then the "current" pie sector will be rendered with the default edge width. If <beg_sect_no> is "ALL" or "0" and <end_sect_no> is not received or is blank, then <3d_depth> applies to all pie sectors.

If <beg_sect_no> and <end_sect_no> are both received and are both numeric integers, then <3d_depth> applies to the range of pie sectors from <beg_sect_no> thru <end_sect_no> and is stored in the corresponding pie sector specs.

If <beg_sect_no> is received and is a numeric integer and <end_sect_no> is not received or is blank, then <3d_depth> applies only to the <beg_sect_no> pie sector and is stored in the <beg_sect_no> pie sector spec.

If <beg_sect_no> and <end_sect_no> are both not received or are blank, then <3d_depth> applies to the "current" pie sector and is stored in the "current" pie sector spec.

Any pie sector specs that are referenced but which do not exist are automatically created and initialized so that the <3d_depth> can be stored.

The last pie sector spec updated becomes the "current" pie sector spec.
