+## Only one integer 0-255 can be returned. Use stdout for other data.
+
+### Problematic code:
+
+    myfunc() {
+      return foo bar
+    }
+
+### Correct code:
+
+    myfunc() {
+      echo foo
+      echo bar
+      return 0
+    }
+
+### Rationale:
+
+In bash, `return` can only be used to signal success or failure (0 = success, 1-255 = failure).
+
+To return textual or multiple values from a function, write them to stdout and capture them with command substitution instead. 
+
+See [[SC2152]] for more information.
+
+### Exceptions:
+
+None
