WriteLn does the same as Write for text files, and emits a Carriage Return - LineFeed character pair after that. If the parameter F is omitted, standard output is assumed. If no variables are specified, a newline character sequence is emitted, resulting in a new line in the file F.
| Remark: | The newline character is determined by the slinebreak constant. |
| Remark: | When writing string variables, no codepage conversions are done. The string is copied as-is to the file descriptor. In particular, for console output, it is the programmer's responsibility to make sure that the codepage of the string matches the codepage of the console. |
More details can be found in the Write description.
If an error occurs, a run-time error is generated. This behavior can be controlled with the {$I} switch.
