[Zope] mid function

[Hamzat kamal]

I checked through the DTML function i could not find this function.
I am writing a code where i will need to store the title of each dtml
document with <dtml-let > and extract certain number of xters from the
title and test it before calling a particular object.

This function is widely used, but this is the way is been used in Vb

mid(string, start [,length])
  string - denote the var name 
  start  -   "    where you want to begin the extraction
  length -   "    the no of xters you want extract from the string

E.g.

let say my title is sunday05082001
then if i specify mid(title, 1, 6)
the result of the fuction will be sunday.

kindly help me out.
