Re^3: Retain first 4 characters of a string

I didnt get you exactly. Do you want to conserve (not trimming to 4 letters) the string "x41212"? (model number)

Sagar, I have changed the requirement slightly, basically the colours below: `baby blue baby pink black dark blue brown dark purple green orange hot pink light purple red white yellow` [download] If the space between them exists then how do i retain just the first letter of the words e.g hot pink would be hp and light purple would be lp? I can't figure out how to do it with the split and join if there is no space between two words then simply retain the colour i.e. red would be red Thank you :)	[reply] [d/l]

Really? When you specify the number of times to match, enter 1	[reply]
