RPG Cafe: Spring 2023: %SPLIT to handle all separators



RPG enhancement delivered through PTFs in the spring of 2023. %SPLIT to handle all separators


You are in: RPG Cafe > RPG Cafe: Spring 2023: %SPLIT to handle all separators

Short URL:


If you use %SPLIT with *ALLSEP in your program, you need a runtime PTF on any system where you run the program. If the runtime PTF is not applied on the system where the program is running, the call to the program fails with MCH4437 saying that a program export is not found.

Spring 2023: %SPLIT to handle all separators

When *ALLSEP is specified for %SPLIT, every separator is considered to separate two substrings. If the string begins or ends with a separator, or one separator immediately follows another, an empty string substring is returned for that separator.


          dcl-s string varchar(200);
          dcl-s s varchar(20);

          string = ',,television,5,,1 Elm Street,,';\

          // With *ALLSEP
          for-each s in %split(string : ','  : *allsep );
             dsply s;
             // values for s in the for-each loop:
             //    1  (empty string)
             //    2  (empty string)
             //    3  "television"
             //    4  "5"
             //    5  (empty string)
             //    6  "1 Elm Street"
             //    7  (empty string)
             //    8  (empty string)

          // Without *ALLSEP
          for-each s in %split(string : ',');
             dsply s;
             // values for s in the for-each loop:
             //    1  "television"
             //    2  "5"
             //    3  "1 Elm Street"
