TRY [CATCH]

TRY [CATCH]

Alternate usage of BEGIN SEQUENCE

Syntax

       TRY
             <statements>
          [CATCH [<exp>] ]
             <errorHandling>
          [FINALLY
             <guaranteed> ]
       END      

Description

TRY/CATCH struct is similar to BEGIN/SEQUENCE struct:

         #xcommand TRY => BEGIN SEQUENCE WITH {| oErr | Break( oErr ) }
         #xcommand CATCH [<!oErr!>] => RECOVER [USING <oErr>] <-oErr->
         #xcommand ENDTRY => END

Alternatively TRY [CATCH] [FINALLY] statements are available on xHB library working like the SEQUENCE construct.
