Error handling statement to set the current error handler

Error Handling Functionskeyworddocumented

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.

Remarks

Differences from QB

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

Example

'' 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
