FIRST() and LAST() - where are the docs?

[dukester]

Can't find them nowhere at:
https://modula3.github.io/cm3/tutorial/m3/m3_toc.html

I'm trying to track down this error:

new source -> compiling sandbox.m3
"../sandbox.m3", line 14: actual not assignable to VALUE formal (2.3.2) (wr)

1 MODULE sandbox EXPORTS Main;
2
3
4 FROM IO IMPORT Put, PutInt;
5 <FATAL ANY>
6
7 CONST MaxPlaces = 11;
14 PutInt(FIRST(INTEGER), MaxPlaces);Put("\n");

It says, that you try to assign the constant MaxPlaces to the second parameter of PutInt which has the name "wr".

And the solution is? I - am not trying to do anything of the sort! I got the code from the Laszlo Boszormenyi/Carsten Weich book: "Programming in Modula-3". Working through the examples and porting them to CM3 as needed - if I can. See: https://www.dropbox.com/s/6jons9npq4qnpaq/M3-min-max-code.jpg?dl=0

The example you're copying uses the "Simple input/output" interface SIO which was invented for the book (pg. 50). The IO module has a slightly different interface.

Thx! Is there an index/glossary - in one location - for everything in CM3?

The example you're copying uses the "Simple input/output" interface `SIO` which was invented for the book (pg. 50). The `IO` module has a slightly different interface. https://modula3.github.io/cm3/help/gen_html/libm3/src/rw/IO.i3.html

CM3's IO.PutInt has no "length" field! Nice trick! Modula-3 is not standardised?

SIO is not part of what is standardized, which is Modula-3 itself and the library code in the required interfaces.  I suppose I would call the things in "Some useful interfaces" defacto standards.  But anybody can write their own library code and publish it, like SIO. It would have been better if the book had either named procedures differently from widely-used libraries or used qualified references, i.e. IO.PutInt or SIO.PutInt.  I almost always use qualified references to anything imported.  Saving confusion later seems more important that saving keystrokes now.
