====== Region Blocking ======

=== Published 19 APR 2018 at 11:44:24AM ===

One small (but useful!) feature we added to the Basic+ editor was the use of "region blocks" to help with code organization in large programs. The blocks group together related sections of code under a descriptive name so they may be navigated and handled more easily (those of you who have programmed in other languages such a C# and C++ might be familiar with this concept already). Essentially region blocks are simply a pair of statements ( "#region" and "#endregion") that you insert before and after a block of code to define it, along with a name that describes the region.  Once you have done this the entire region becomes a "fold point", so it can be folded to hide it, and it also appears as a "jump point" in the editor navigation dropdown so you can get to it quickly. E.g.

<code>
#region ScrollMode

// Here's some code for handling the ScrollMode property in the FormDes etc...
onParseStruct_HandleScrollMode:
   if bitAnd( psPSStyleEx, PSSX_VIEW_SCROLLMODEPAGING$ ) then
      psWinStyle = bitOr( psWinStyle, WS_VSCROLL$ )
   end
return

// More stuff ....
#endregion ScrollMode
</code>

This now becomes a fold point in the editor: [caption id="attachment_2839" align="aligncenter" width="625"][[http://revdevx.com/2018/04/19/region-blocking/region-folding/|{{18372.4891666667_1.png}}]] Region Folding[/caption] And can be jumped to in the navigation dropdown like so: [caption id="attachment_2840" align="aligncenter" width="542"][[http://revdevx.com/2018/04/19/region-blocking/region-dropdown/|{{18372.4891666667_2.png}}]] Region Dropdown[/caption] So, if you do have some programs with large amounts of code hopefully this feature might help find your way around it quicker.
