Overview</A></H1><P>The GridTurtle test programs are a collection of programs      which exercise basic capabilities of the defobj, collections,      and activity libraries.  These programs are always run on each      new release of these libraries as a partial test.  For the time      being they also serve to show examples of working code that      exercise basic capabilities or accomplishes particular tasks.    </P><P>Note, however, that these are not good examples to learn      from, or examples to emulate!  The programs are not particularly      well-designed as either a systematic test or a useful series of      tutorial examples, but until there's anything else they help      serve for both.  To serve their role as test programs some of      these examples deliberately make use of the more obscure and      low-level features of the libraries they exercise.  Mixed in are      examples of many basic code fragments an application might need.      So be selective in what you use, and read the comments on each      program below.    </P><P>Most of the programs in this directory use a simple type of      object called a "GridTurtle."  This type of object is an agent      that move around on a two-dimensional grid, always moving in a      current direction that it maintains internally.  This agent is      like a "turtle" of the original Logo system, except that its      position is constrained to discrete integer values of its X-Y      coordinates, and its direction is always one of the four      orthogonal directions north, east, south, or west.  The      GridTurtle object type is implemented using the <AHREF="swarm.library.sgml.appendix.html">library interface      conventions</A> of the <AHREF="swarm.defobj.sgml.reference.html">defobj</A> library, and is      itself a defined module that must be initialized by any program.    </P></DIV></DIV><DIVCLASS="NAVFOOTER"><HRALIGN="LEFT"WIDTH="100%"><TABLEWIDTH="100%"BORDER="0"CELLPADDING="0"CELLSPACING="0"><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top"><AHREF="swarm.space.generic.module.html">Prev</A></TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="set.html">Home</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top"><AHREF="x23494.html">Next</A></TD></TR><TR><TDWIDTH="33%"ALIGN="left"VALIGN="top">General</TD><TDWIDTH="34%"ALIGN="center"VALIGN="top"><AHREF="book930.html">Up</A></TD><TDWIDTH="33%"ALIGN="right"VALIGN="top">Summary of files</TD></TR></TABLE></DIV></BODY></HTML>
