Description

The SAVE ERROR command saves the error.mem information to a specified file <mem filename> when an error occurs. This includes the following information:

• Recital Software version, patch release and compilation date
• Date and time file created
• Machine and user names
• Stack trace
• Active public and private procedures and functions
• Public and private memory variables
• Active status of workareas
• Settings as per DISPLAY STATUS

The SAVE ERROR command should be used in conjunction with the ON ERROR command. NOTE: multiple numbered error.mem files can be created automatically if SET ERRORVERSION is ON.

Example

procedure errproc
  on error
  lerrflag = .T.
  save error to errlog
return
 
// Attempt to open non-existent table
lerrflag = .F.
on error do errproc
use nontable
if not lerrflag
    // Continue processing
else
    dialog box "Error has occurred"
endif
