+---------------------------
+Jason's Scratchpad: 
+---------------------------
+
+Namespace Scope
+---------------
+(NOTE: This is partially language-dependent)
+
+
+All Objects: 
+ * "self" refers to the object containing the trigger (not the trigger 
+   object).  For example, if a block contains a "pre-focusin" trigger, 
+   then "self" within that trigger refers to the block.  This is true 
+   even for named triggers.  (Python specific)
+
+
+Global Namespace: 
+ * all page names
+
+ * all datasource names
+
+ * all blocks???
+
+ * "form" contains information specific to the current form (or "report", 
+   etc).  Possible attributes for "form" are GetCurrentBlock(), 
+   GetCurrentPage(), and GetCurrentField(), as well as all page names, 
+
+
+Pages: 
+ * All block, label, etc names located in the page (but not within blocks)
+
+
+Blocks: 
+ * all entry, label, etc names in the block
+
+ * jump(#)   (Move to record #)
+
+ * record()
+
+ * first()
+
+ * last()
+
+ * isfirst()
+
+ * islast()
+
+ * count()
+
+ 
+
+Fields: 
+ * sum() adds all the fields 
+
+ * count() returns a count of the fields that are non-null
+
+ * 
+
+  
+========
+findObject("myblock.myfield")
+
+ * For non-OO languages
+  
+ * For object names that cause problems in namespace
+
+========
+Convenience functions: 
+  myblock.field.sum()
+  myblock.field.count()
+  myblock.count()
+
+
+========
+How should we handle code other than triggers.
+
+
+
+Object Translation Services???
+------------------------------
+
+ <input name="myfield">
+   <import-trigger name="positiveTrigger"  ...  translate="field=myfield"/>
+ </input> 
+
+  ...
+
+ <trigger name="positiveTrigger"> 
+    if field.value < 0: 
+      gnue.warn( "%s must be at least 0" % field.getDescription() )
+      return 1
+    else: 
+      return 0
+  </trigger>
+
+  This way, positiveTrigger can be reused in many forms, even if the field 
+  name changes.
