You get the idea.. A whole load of data seperated by "/" foward slashes. What I need is something to find the fist set of "//" doubles and insert text between them.
Its been a while since I've done anything like this and I can't find a solution in any of my old scripts. Seeing as I've only been at it for less than a year I don't have many old scripts that I've kept.
I appriciate any help you can give.
Thanks in advance

All the Best, Eoin...

If everything seems to be going well, you obviously don't know what the hell is going on.

to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
