+<h3>Executing programs</h3>
+
+<i>Game Maker</i> also has the possibility to start external programs. 
+There are two functions available for this: execute_program and execute_
+shell. The function execute_program starts a program, possibly with some 
+arguments. It can wait for the program to finish (pausing the game) or 
+continue the game. The function execute_shell opens a file. This can be 
+any file for which some association is defined, e.g. an html-file, a word 
+file, etc. Or it can be a program. It cannot wait for completion so the 
+game will continue.
+
+<p>
+<blockquote>
+  <tt><b>execute_program(prog,arg,wait)</b></tt> 
+    Executes program prog with arguments arg. wait indicates whether to wait for finishing.<br>
+  <tt><b>execute_shell(prog,arg)</b></tt>
+     Executes the program (or file) in the shell.<br>
+</blockquote>
+
+<p>
+Both functions will not work if the player sets the secure mode 
+in the preferences. You can check this using the read-only variable:
+
+<p>
+<blockquote>
+  <tt><b>secure_mode*</b></tt> 
+    Whether the game is running in secure mode.<br>
+</blockquote>
