Functional Problems Addressed

• The following deficiencies have been resolved:
  • Lack of Exception Handling.
  • When creating a new variable if it started with I% it should be forced to an Instance and the I% stripped. Likewise so should a C% be forces as a Class Variable.
  • V of $NULL will hang the system.
  • Browsing Large Object causes a problem.
  • Event Command should allow interface to be specified.
  • Options: section allows "Type=".
  • Sync not changing Tab.
  • Nested class appears wrong when foreign on a re-load.
  • Type/Method checks at compilation (Warning).
  • Have Do check the Label.
  • Move the Parsing table to ^VESOI.
  • Instance variable undefined problem.
  • Fix Weird cache Connect problem.
  • Fix CompileClassDefs for Compilation of the routine.
  • Sync does not scroll the item into view when it is already selected.
  • In Object Browser Ctrl+C (Class) does not appear to work.
  • Folders that export Libraries can not be imported if the Library does not exist.
  • Debug Compile of UI gets an exception when creating a Variable that has a single character name.
  • Possible Points of Optimization Addressed
  • Create a compiled InitAllSysVar Method.
  • Global Call Cache.
  • Remove or Rework $Handle & %objcf(%objsp,19).
  • Use the $7 & $8 Compiled Tables.
  • Remove intercall error trap.
