Nope. Because the way I would do this in LCS doesn't exist in LCB. The 
LCB syntax is actually more intuitive, but getting to that point took 
all morning. Having to read between the lines in the dictionary and make 
guesses (educated and non) about the keywords and syntax.

I wasn't dealing with IP addresses, just converting #NNNNNN colors to 
(DDD,DDD,DDD) format, two hex digits at a time. Along the way I 
discovered interesting things like the fact that 'comma' isn't a defined 
constant in LCB. And that there's no concept of word chunks in LCB.

And there's afaict no messagebox-style way to interactively try out the 
possible syntax forms - you just have to write the code, try to compile 
it, and then try to figure out why there's a syntax error.
