UpcaseLowcase

[elsalam]

I have been trying to figure it out how to solve this question for two days but no luck yet.  Hope you can help.

Q)  Convert all consonants in the values for the City and Team variables to uppercase letters and all vowels in the values for the City and Team variables to lowercase letters.

Note: Overwrite the original values with the new values   Refer the detail to the attachment.

if anydigit (team) then numbert =1;
else numbert = 0;
CityTeam = catx('-',city,team);

array CTL (3) $ city Team Cityteam;

do lowcase = 1 to substr('City',2,1);

If substr(lowcase(City),2,1) in ('a','e','i','o','u') then CTL (lowcase) = lowcase;
else CTL (lowcase) = upcase;

end;

else superbowl = 'not a contender';

Hi:

  I agree with a DO loop, I'm not sure you need an ARRAY, since the TRANSLATE function will work for you. I did not consider 'y' to be a vowel for this example. Also, I did NOT overwrite the original values because I wanted to show my work in progress (TmpStr, NewCity and NewTeam):

  Here's the code I used:

data sports;
  length City NewCity $15 Team NewTeam $12 TmpStr  $30 uchar $1;
  infile datalines dlm=',' dsd;
  input @1 City $ year Team $;
  TmpStr=upcase(catx('~',City,Team));
  do ck = 'a', 'e', 'i', 'o', 'u';
    uchar = upcase(ck);
    TmpStr = translate(TmpStr,ck,uchar);
  end;
  NewCity = scan(TmpStr,1,'~');
  NewTeam = scan(TmpStr,2,'~');
return;
datalines;
Baltimore, 2012, Ravens
Cincinnati, 2012, Bengals
Cleveland, 2012, Browns
Pittsburgh, 2012, Steelers
Chicago, 2012, Bears
Detroit, 2012, Lions
Green Bay, 2012, Packers
;
run;
  
proc print data=sports;
var City NewCity year Team NewTeam TmpStr;
run;

[PGStats · Accepted solution]

I would do:

data sports;
  length City $15 Team $12;
  infile datalines dlm=',' dsd;
  input @1 City $ year Team $;
from = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
to =   "aBCDeFGHiJKLMNoPQRSTuVWXyZ";
city = translate(upcase(city),to,from);
team = translate(upcase(team),to,from);
drop from to;
datalines;
Baltimore, 2012, Ravens
Cincinnati, 2012, Bengals
Cleveland, 2012, Browns
Pittsburgh, 2012, Steelers
Chicago, 2012, Bears
Detroit, 2012, Lions
Green Bay, 2012, Packers
