writeln
Usage
writeln (f)
writeln (f, e)
writeln (f, e1, ..., en)
writeln
writeln (e)
writeln (e1, ..., en)
Parameters
f A file variable for a text file opened in the output state. The
system uses the standard file output if f is omitted.
e A variable or expression whose type is not FILE and does not contain
a component of type FILE.
Description
The procedure writeln (f, e) writes the value of the expression e to the
textfile f , appends an end-of-line marker, and places the current
position immediately after this marker. After execution, the file buffer
f^ is undefined, and eof (f) is true. You may write the value of e with
the formatting conventions described for the procedure write.
The call writeln (f, e1,..., en) is equivalent to
write(f,e1);
write(f,e2);
.
.
.
write(f,en);
writeln(f)
The call writeln without the file or expression parameters effectively
inserts an end-of-line marker in the standard file output.
Example
writeln(fil_var)
writeln(fil_var,exp:4)
