When implementing the function asin() for complex arguments in Proc Mbasic

I discovered errors on page 80, formulas 4.4.37 and 4.4.38, in "Handbook of

Mathematical functions" by Abramowitz & Stegun. It is corrected in the file

below. "NIST Digital Library of Mathematical Functions", avaliable at

http://dlmf.nist.gov/, is a modern comprehensive reference to mathematical

functions, which does not contain the errors. But since Abramowitz & Stegun

is still widely used, if for no other reason than that mathematicians have

learned their way in it, any correction to it needs to be publicly known.
