==== Compiler problem with Inserts (OpenInsight 32-bit Specific) ====

<QUOTE>
It appears that the compiler does not like a $INSERT to be on the first line -

 If I compile this -



 FUNCTION DEMOTE (FIELD, DUMMY)

_____ $INSERT ARGNOSIS_INSERTS, ARRAY_PROMOTION

_____ DEMOTED=FIELD

_____ CONVERT PROMOTED_ARRAY@ TO DEMOTED_ARRAY@ IN DEMOTED

 RETURN DEMOTED



 I get this error message -

 B102:  Line 2.  Illegal Statement:  $INSERT ARGNOSIS_INSERTS,ARRAY_PROMOTION.



 If I compile this -



 FUNCTION DEMOTE (FIELD, DUMMY)

 ******************

_____ $INSERT ARGNOSIS_INSERTS, ARRAY_PROMOTION

_____ DEMOTED=FIELD

_____ CONVERT PROMOTED_ARRAY@ TO DEMOTED_ARRAY@ IN DEMOTED

 RETURN DEMOTED

 It compiles just fine.







 P.S. Note the astute use of the DUMMY argument

<QUOTE>Off the top of my head, two reasons



 1. I like DUMMY arguments so much that I can foresee Revtech enforcing

255 arguments per Subroutine (and 254 for Functions of course),

so I am including a DUMMY argument in ALL calls.







 2. The dummy argument allows me to extend the language syntax.

E.g.

 The DIRLIST function can now be both local and global -

_____ DECLARE SUBROUTINE DIRLIST

_____ FILES=DIRLIST()

_____ ECHIDNAS=DIRLIST(DUMMY)



Wow!

<QUOTE>That is 

DECLARE FUNCTION DIRLIST, not SUBROUTINE - sorry about that

<QUOTE>Peter,



By Odin, you're right.



An empty line also does the trick. That's what's kept me from discovering it. I always have an empty line after the function or subroutine statement.



Btw - here's something else the compiler doesn't like: a comment line between begin case and the first case.

<QUOTE>Peter,



That's a relief. I feared you'd taken my ramblings about dummy arguments a month ago seriously. :-D

I enjoy a productive argument.

I like the topic.
