Body
So if I have a recursive function with a global variable var_: <pre><code>int var_; void foo() { if(var_ == 3) return; else var_++; foo(); } </code></pre> and then I have a function that calls foo() so: <pre><code>void bar() { foo(); return; } </code></pre> what is the best way to set var_ =0 everytime foo is called thats not from within itself. I know I could just do: <pre><code>void bar() { var_ =0; foo(); return; } </code></pre> but I'm using the recursive function a lot and I don't want to call foo and forget to set var_=0 at a later date. Does anyone have any suggestions on how to solve this? Thanks, Josh

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
