Resume

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

Example
   '' 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

Dialect Differences
   *  RESUME is not supported in the -lang fb dialect. Statements can be 
     used in its function form to return an error code
   If Open( "text" For Input As #1 ) <> 0 Then
     Print "Unable to open file"
   End If

 

Differences from QB
   * Does not accept line numbers or labels
   * Must compile with -ex or -exx option
