Here's an example that doesn't work with the default, but does with
*resdecpos.  The wisdom of multiplying 3 15,5 numbers into a 15,5 result is
questionable, but.....

 Dresdec           c                   const('Using *resdecpos : ')

 Ddefault          c                   const('Using *maxdecpos : ')

 Dnum1             s             15p 5 inz(1)

 Dnum2             s             15p 5 inz(1)

 Dnum3             s             15p 5 inz(  .1)

 Danswer           s             15p 5

 Dresult           s             51

 Dresponse         s              1

 C                   eval      answer = num1  * num2 * num3

 C                   eval      result = default + ' ' + %editc(answer : 'J')

 C     result        dsply                   response

 C                   eval(r)   answer = num1  * num2 * num3

 C                   eval      result = resdec + ' ' + %editc(answer : 'J')

 C     result        dsply                   response

 C                   eval      *inlr = *on
