The unit sysUtils shipped with the FPC’s default run-time library provides many system utilities.
It attempts to be as compatible to Delphi’s sysUtils unit as possible.
However, the FPC version is available on all platforms that the FPC supports.
It does not contain any Windows-related routines or other highly platform-specific functionality.
Notable functionality
Caveats
If the sysUtils unit is included, all run-time errors become exceptions, which virtually forces you to use a compiler mode (or mode switch) that allows exception treatment.
You will need to include sysUtils in every unit that may throw an exception, even though the unit itself does not use any of the included system utilities.
