Using the data set Mixed, create a temporary SAS data set (also called Mixed) with the following new variables:

a. NameLow Name in lowercase

b. NameProp Name in proper case

I tried this but not working

data mixed; input Name & $20. ID; datalines; Daniel Fields 123 Patrice Helms 233 Thomas Chien 998 ; proc print data = mixed; out learn.mixed replace; NameLow = lowcase(Name); NameProp = propcase(Name); run; title "Listing of data set mixed"; proc print data = mixed; run;
