[Wrapl-discussion] K(expr1, ..., exprN)

[Roman M. <rom...@gm...>]

Hello.

I am going through the Wrapl's tutorial and am trying to employ this
function call: K(expr1, ..., exprN).
I understand how it is intended to work and if K is an explicit integer, it
works as expected, but if K is calculated, only expr1 is selected, no more.

For example:

MOD bottles;

IMP IO.Terminal USE Out;

VAR s <- "s"; DEF ob <- "of beer"; DEF otw <- "on the wall"; VAR i;
EVERY i <- 9:to(0,-1) DO (
((2 > i) + 1)(s <- "s", s <- "");
Out:write('{i} bottle{s} {ob} {otw}.\n');
);

END bottles.

outputs:
...
2 bottles of beer on the wall.
1 bottle of beer on the wall.
0 bottle of beer on the wall.

I want it to be:
...
2 bottles of beer on the wall.
1 bottle of beer on the wall.
0 bottles of beer on the wall.

I am on Windows XP, Wrapl [1.1.5:864].
