$$Caseconvert was released in version 3.6 and I have older version than that That is why its showing error "Function: CaseConvert definition not found"
Is there a workaround for it to work in the older version? If you could give me the $$CaseConvert function source code, I can add it in my TDL, and try it.
Source code not available (you can search in Developer, if it is there or not) ....... and .......... Yes there is a work around......... you need to buy licensed software and upgrade the version.
