eclipse templates -- creating and setting a permanent variable
In eclipse (java) Window->Preferences->Java->New new templates can be created.
In the field "Pattern" I entered
System.out.println("DEBUG ${label}");
${cursor}
I like old-style debugging, so I use a lot statements like System.out.println("DEBUG A"); ... System.out.println("DEBUG Z");.
The question is, can (and if so, how) I have the variable ${label} to be permanent and auto-increasing?
So that calling it first time, it has value "A", second time "B" and so on.
The question is not restricted to the use-case above, templates are a mighty tool, if you know how to use it.

I can't think of a way to remember and increment a counter in templates. However, if you're content with a random number rather than an incrementing counter, then using a date template variable should work. As an example:
System.out.printf("Debug %d\n", ${d:date('S')});
This template will insert a date specifying only the number of milliseconds. In practice, this is just a random 3-digit number. If you want an even longer number to reduce the risk of collision, you could include the seconds as well:
System.out.printf("Debug %d\n", ${d:date('sS')});
The date is formatted according to java.text.SimpleDateFormat. Documentation for templates can be found here.
