:: Actually, the mathematical constants may be referred to by a predefined or reserved identifier in some languages. If this is the case, then I suggest that we include those too. --[[User:Markhobley|Markhobley]] 16:37, 12 June 2011 (UTC) |

== REXX Special variable RETURN == |
|||
Just a summary of a long offline discussion and the facts as I see them |
|||
<br> REXX version 1 states RESULT [the result RETURNed from a subroutine or function] |
|||
<br> The REXX standard and several implementations (Regina, VM, TSO) state that RETURN is set after subroutine calls and not after function invocations. |
|||
<br> Some other (older) implementations set it also after function invocations, thereby violating the standard (which was, I think, only created at a later point in time). |
