Resume

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

'' 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

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

  Print "Unable to open file"
