I understand that this ago cry,
but write a true solution it require very more code:

ss="Global Traders (pvt) Ltd."
* you can use 9,10,11,12,13,32,160 to translate a prefix char to a proper prefix char
* if char(11) it is out of data domain 
? CHRTRAN(PROPER(CHRTRAN(m.ss,'(',CHR(11))),CHR(11),'(')
