>[snip]... Peter: what happens if STRINGRANGE is disabled?
As the message says, the third argument (5) will be trimmed to fit (i.e.
3 will be used). For the following source code
TEST09: PROC OPTIONS(MAIN);
DCL SOURCE CHAR(10) INIT('0123456789');
DCL TARGET CHAR(10) VAR INIT('');
TARGET = SUBSTR(SOURCE, 8, 5);
END;
the compiler produces these object code statements (only the statements
or interest shown)
MVC SOURCE(10,r13,180),'0123456789'(r1,0)
MVC TARGET(3,r13,170),SOURCE(r13,187)
MVHHI TARGET(r13,168),H'3'
