Hi Folks
I'm working on the Rational for Z to develop PL/i for mainframes,
and a little question about substr,
the following is my code fragment:
------------------------------start of
code------------------------------
dcl long_char char(300) ;
dcl temp_char char(10) ;
dcl substr builtin;
long_char = '?HELLO,??WORLD!I?LOVE?THIS?COUNTRY,?I?LIKE?IT?SO? MUCH!';
temp_char = substr(long_char,cur,10);
display(long_char);
display(temp_char);
----------------------------------end of
code---------------------------
---------------------------------display----------------
?HELLO,??WORLD!I?LOVE?THIS?COUNTRY,?I?LIKE?IT?SO?M UCH!'
?HELLO,??
i suppose the first 10 characters the machine displayed will be the
same, for the temp_char, there is always one more leading blank, i
can't figure it out, anybody can help for that?
Tks!!!

Where do you set the value of cur, the starting position of the
substring function?
