 The `catch` statement runs a series of substatements in a block, but only if the previous xref:unlang/try.adoc[try] failed.
 
-[ rcodes ]:: Zero or more module return codes.  The return codes can be `disallow`, `fail`, `invalid`, `timeout`, or `reject`.
-+
+<return codes>:: Zero or more xref:unlang/condition/return_codes.adoc[return codes].
 
 [ statements ]:: The `unlang` commands which will be executed.  A `catch` block can be empty.
 
-If no rcode is given the `catch` statement matches all of the codes listed above.  Otherwise, the `catch` statement matches one of the listed rcodes.
+If no return code is given, then the `catch` statement will match all of the return codes.  Otherwise, the `catch` statement matches only the return codes which were listed.
 
-Multiple `catch` statements can be placed one after the other, to `catch` different errors.  Only one of the statements will be executed.  Once a `catch` statement is finished, the interpreter will skip all trailing `catch` statements, and continue execution
