Joseph is right....what is needed is for STRING() to allow a
floating format descriptor like F0.2 that works like I0...creates a
string of just enough characters to contain the float of appropriate
precision, akin to using "%.2f" in sprintf() in C. I was disappointed
to find that F0 was not allowed...I use I0 all the time. As far as
tightening up your code, you could define a function to do the
combined operation. And wouldn't STRTRIM( ,1) suffice, since STRING()
is just inserting leading, not trailing blanks?
