Error handling statement to set the current error handler

Syntax

` On Local Error Goto label

`

Description

The Local clause in an On Error construction allows to define an error handler in the same Sub or Function the On Local Error is in.

Remark: Presently, the Local clause (authorized only inside Sub/Function) is ignored by the compiler, and the error handler should be in the scope of the same procedure the On [Local] Error is in.

Examples

start GeSHi

'' compile with -lang fblite or qb

#lang "fblite"

Declare Sub foo

foo
Print "ok"
Sleep

Sub foo
  Dim errno As Integer
  On Local Error Goto fail
  Open "xzxwz.zwz" For Input As #1
  On Local Error Goto 0
  Exit Sub
fail:                  ' here starts the error handler
  errno = Err
  Print "Error "; errno      ' just print the error number
  Sleep
End Sub

end GeSHi

Differences from QB

• The LOCAL clause comes from PDS 7.1. QB 4.5 does not allow local error handling.
