užitečné v případě, kdy chcete vrátit hodnotu, řekněme ze smyčky, nebo když pracujete s návratovými hodnotami

+this should be second nature. However genius can let you pretend it is a
+terminator to some degree.  If a <literal>;</literal> is found at the end of a parenthesis or a block,

+This will require some parenthesizing to make it unambiguous sometimes,
+especially if the <code class="literal">;</code> is not the top most primitive. This slightly differs from
+other programming languages where the <code class="literal">;</code> is a terminator of statements, whereas
+in GEL it’s actually a binary operator. If you are familiar with pascal
+this should be second nature. However genius can let you pretend it is a
+terminator to some degree.  If a <code class="literal">;</code> is found at the end of a parenthesis or a 
block,
+genius will append a null to it as if you would have written
+<strong class="userinput"><code>;null</code></strong>.
+This is useful in case you do not want to return a value from a loop,
+or if you handle the return differently.
+      </p><p lang="en">
+             If you are typing expressions in a program file you do not have to add a semicolon.  In this 
case
+             genius will simply print the return value whenever it executes the expression.  This is the same
+             as when typing on the command line.  However, do note that if you are defining a
+             function, the body of the function is a single expression.  Usually, therefore, if a function 
body is
+             long, you will need to enclose it in parentheses.

un programa <a class="link" href="ch05.html" title="Chapter 5. Conceptos de GEL">GEL</a> en esta área de 
trabajo. Una vez que haya escrito su programa, puede ejecutarlo desde <span 
class="guimenu">Calculadora</span> → <span class="guimenuitem">Ejecutar</span> (o el botón de la barra de 
herramientas <span class="guilabel">Ejecutar</span>). Esto ejecutará su programa y mostrará cualquier salida 
en la pestaña <span class="guilabel">Consola</span>. Ejecutar un programa es equivalente a tomar el texto del 
programa y escribirlo en la consola. La única diferencia es que esta entrada se realiza independientemente de 
la consola y solo la salida va hacia la consola. <span class="guimenu">Calculadora</span> → <span 
class="guimenuitem">Ejecutar</span> siempre ejecutará el pr
 ograma actualmente seleccionado incluso si se encuentra en la pestaña <span class="guilabel">Consola</span>. 
El programa actual tiene su letra en negrita. Para seleccionar un programa, simplemente pulse sobre su 
pestaña.</p><p>Para guardar el programa que acaba de escribir, elija <span class="guimenu">Archivo</span> → 
<span class="guimenuitem">Guardar como...</span>. Al igual que en otros programas puede elegir <span 
class="guimenu">Archivo</span> → <span class="guimenuitem">Guardar</span> para guardar un programa que ya 
tenía un nombre asignado. Si tiene muchos programas abiertos que ha editado y quiere guardarlos, puede 
hacerlo eligiendo <span class="guimenu">Archivo</span> → <span class="guimenuitem">Guardar 
todo</span>.</p><p>Los programas que no han guardado los cambios todavía, tienen un símbolo «[+]» junto al 
nombre de archivo. Así puede ver si el archivo en la pestaña actual y el que está guardado en el disco, 
difieren en su contenido. Los programas que no se
  han nombrado todavía, se consideran siempre como no guardados, por lo que no se muestra el símbolo 
«[+]».</p></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td

du inte vill returnera ett värde från exempelvis en slinga, eller om du vill hantera returvärdet på annat

+terminator to some degree.  If a <literal>;</literal> is found at the end of a parenthesis or a block,
+genius will append a null to it as if you would have written

body is
