%prodlist (%nrstr(clothes&shoes)) In the provided code, when the %str( &) is present in the title statement, the title displayed in the report becomes "Listing of Clothes&Shoes." On the other hand, if the %str( &) is omitted and the title statement is written as "title "Listing of %qsysfunc(propcase(&prodline))";", the title in the report appears as "Listing of Clothes&shoes." I'm curious why, when %str( &) is omitted, the propcase function doesn't seem to apply to the word "Shoes" in the title. Could you please explain why this happens?
