2  Description
   The FIRST command is one of a series of directional commands
   that allows you to traverse a program's structure. The FIRST
   command displays the current traverse subtree and positions
   an arrow to point to the bucket with the most data points. The
   corresponding source lines for that portion of the program are
   displayed alongside the plot. Other traverse commands are NEXT,
   BACK, and CURRENT.
