Re: [Jmol-developers] new proposed text utility function (or do we have it somewhere?)...

[Robert H. <ha...@st...>]

I suppose it all depends upon how many times you have to do it and how long
the string is. I thought you were counting words -- what you are doing is
counting characters? then the following is the easiest:

c = a.trim() + " " + b.trim()

or

c = (a[1][n]).trim() + " " + b.trim()


There's not much advantage in doing the checks. Just trim and add.

If nature does not answer first what we want,
it is better to take what answer we get.
