Certain errors at run time cause Delphi programs to display an error message and terminate.

Identifying Run-time Errors

Run-time errors take the form:

Run-time error nnn at xxxxxxxx

where nnn is the run-time error number, and xxxxxxxx is the run-time error address.

Applications that use the SysUtils class map most run-time errors to Exceptions, which allow your application to resolve the error without terminating.

Types of Run-time Errors

Delphi run-time errors are divided into the following categories:

  • I/O errors, numbered 100 through 149
  • Fatal errors, numbered 200 through 255
  • Operating system errors
