Error handling statement to resume execution after a jump to an error handler

Syntax

` Resume

`

Description

Resume is used in the traditional QB error handling mechanism within an error handler (called by On Error) to return execution to the line that caused the error. Usually this is used after the error has been handled gracefully in order to try the previously erroneous operation again with corrected data.

Resume resets the Err value to 0

Examples

start GeSHi

'' Compile with -lang fblite or qb

#lang "fblite"

Dim As Single i, j

On Error Goto ErrHandler

i = 0
j = 1 / i ' this line causes a divide-by-zero error on the first try; execution jumps to ErrHandler label

Print j ' after the value of i is corrected, prints 0.5

End ' end the program so that execution does not fall through to the error handler again

ErrHandler:

i = 2
Resume ' execution jumps back to 'j = 1 / i' line, which does not cause an error this time

end GeSHi

Dialect Differences

• RESUME is not supported in the -lang fb dialect. Statements can be used in its function form to return an error code

start GeSHi

If Open( "text" For Input As #1 ) <> 0 Then
  Print "Unable to open file"
End If

end GeSHi

Differences from QB

• Does not accept line numbers or labels
• Must compile with -ex or -exx option
