Please read Source Code Indentation for the basic idea first.
Some programming languages support naming a loop and the statements controlling the loop execution
can reference a specific loop. In this case the indentation of the statements reflects the loop they
reference.
An Example:
1: lFiles: for my $FileName ($aFileNames)
2: {
3: my $File= fopen($FileName, 'r');
4:
5: if(!$File)
6: next lFiles;
7:
8: my $Result= '';
9:
10: lLines: while(my $Line= ReadLine($File))
11: {
12: if($Line == '')
13: next lLines;
14:
15: my $Ret= ProcessLine($Line, $Result);
16:
17: if($Ret == 'eof')
18: last lLines;
19:
20: if($Ret == 'abort')
21: next lFiles;
22: }
23:
24: ProcessResult($Result, $FileName);
25: }
|
Here the next and last statements are indented so that they make clear which loop they influence.
