WriteLn

Declaration:
Procedure WriteLn [([Var F : Text;] [V1 [; V2; ... , Vn)]];
Description:
WriteLn does the same as Write (589) 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 Carriage Return - LineFeed character pair is emitted, resulting in a new line in the file F.

Remark: Under LINUX and UNIX, the Carriage Return character is omitted, as customary in Unix environments.

Errors:
If an error occurs, a run-time error is generated. This behavior can be controlled with the {$i} switch.
