Resets error information and indicates what to execute next.

Resume [ [0] | label | Next ]

0 Reinicia la informació d'error i torna a executar la instrucció que ha causat l'error. 0 és opcional.

label: Resets error information and resumes execution at the specified label of the current subroutine.

Next Reinicia la informació d'error i executa la instrucció que segueix a la que ha causat l'error.

Error information is built with Erl, Err and Error$ functions.

• Erl: Module line number where error occurs.

• Err: Error number.

• Error[$] Descripció d'error.

Using Resume to reset error information prevents the propagation of the handled condition to calling routines.

Exemples:

Typical error handling routines are: alerting the user, fixing the error, logging error information or re-throwing custom errors that provide explanations with resolution instructions. Use Resume label when requiring such mechanisms.

Sub Error_Handling
try: On Error GoTo catch
    ' el codi de la rutina va aquí
    Error 91 ' example error
finally:
    ' routine cleanup code goes here
    Exit Sub
catch:
    Print Erl, Err, Error$
    Resume finally
End Sub ' Error_Handling

Use Resume Next, for example, when reporting anomalies encountered for an iterating process that must not be interrupted. In which case multiple handling routines may be required.

Sub Iteration
    planets = Array("☿","♀","♁","♂","♃","♄","⛢","♆")
try:
    On Error GoTo ReportAndProcessNext
    For ndx = -3 To 11 Step 1
        MsgBox planets(ndx)
    Next
    On Error GoTo 0 ' Stop error catching
finally:
    Exit Sub
ReportAndProcessNext:
    Print "Error "& Err &" at line "& Erl &" - "& Error$
    Resume Next
End Sub ' Iteration

Using Resume without parameters to re-execute the faulty instruction can fit certain situations. However that may cause a never ending loop.
