Somehow I always forget that there is a boolean function in ABAP. That’s why I’m writing this post to hopefully remember it better. 🙂
If you just want to check something for truthiness, you can do it in the following three ways:
IF sy-subrc = 0.
result = abap_true.
ELSE.
result = abap_false.
ENDIF.
result = SWITCH #( sy-subrc WHEN 0 THEN abap_true
ELSE abap_false ).
result = xsdbool( sy-subrc = 0 )
Note: Case values are tested with strict equality (===)
/* Default Option in Switch Statements */
var result = "";
switch (num) {
case 1:
result = "1";
break;
case 2:
result = "2";
break;
default:
result = "3 or more";
break;
}
/* Multiple Identical Options in Switch Statements */
var result = "";
switch(val) {
case 1:
case 2:
case 3:
result = "1, 2, or 3";
break;
case 4:
result = "4 alone";
}
