HI Kishore ,

For returning a string without Trailing & Leading Blank spaces can be done by using "Trim" built in function.
( i.e Rtrim,Ltrim,Trim)

Code:

str= "     hai"   ; ltrim(str) --> "hai"

str= "hai    "    ; rtrim(str) --> "hai"

str= "   hai     " ; trim(str) ---> "hai"

If your question is regarding the eliminating leading & trailing blank spaces then , the above solution might be useful to u.
