ChadSmiley Blog :: @UpdateFormulaContext and @Command([Compose])

I found some interesting results using the @UpdateFormulaContext and the Compose command. It looks likes the tempary variables are actually pointers. Notice the difference (shown below) when the database information is stored in the variable instead of a string.

FromTitle := @DbTitle;
FromServerPath := @DbName ;
FromDB := @DbTitle + " | " + @Implode( @DbName ; "!!" );

@StatusBar( "From title " + FromTitle );
@StatusBar( "From path " + @Implode( FromServerPath ; "!!" ) );
@StatusBar( "From DB " + FromDB );

@StatusBar( "Before compose "  );
@Command( [Compose] ;"" : "names.nsf" ; "Person"  );

@StatusBar( "After compose "  );
@StatusBar( "After compose From title " + FromTitle );
@StatusBar( "After compose From path " + @Implode( FromServerPath ; "!!" ) );
@StatusBar( "After compose From DB " + FromDB );

@UpdateFormulaContext;
@StatusBar( "After Update Formula Context "  );
@StatusBar( "After Update Formula Context From title " + FromTitle );
@StatusBar( "After Update Formula Context From path " + @Implode( FromServerPath ; "!!" ) );
@StatusBar( "After Update Formula Context From DB " + FromDB );

@StatusBar( "Names title " + @DbTitle );
@StatusBar( "Names path " + @Implode( @DbName ; "!!" ) );
@StatusBar( "Names DB " + @DbTitle + " | " + @Implode( @DbName ; "!!" ) );

Here are the results:
From title Some Database
From path !!somedb.nsf
From DB Some Database | !!somedb.nsf
Before compose
After compose
After compose From title Some Database
After compose From path !!somedb.nsf
After compose From DB Some Database | !!somedb.nsf
After Update Formula Context
After Update Formula Context From title Someone's Address Book
After Update Formula Context From path !!names.nsf
After Update Formula Context From DB Some Database | !!somedb.nsf
Names title Someone's Address Book
Names path !!names.nsf
Names Someone's Address Book | !!names.nsf
