I want to extract the digit from a line of text. For exmple, for a text line: TSC2101Net, how can I write a script to extract 2101 and print it?
There are number of techniques that spring to mind, the obvious being regular expressions and substring. The latter isn't much good unless you know the position of the numbers in the string. The former is more flexible but also more complex.

Evolved into a distracting blinking thing that gives me a headache. Eugh.
