Hi All,
I am trying to understand how to read variables from the
shell's environment. I am reading this:
https://docs.perl6.org/language/variables#Dynamic_variables
<code>
#!/usr/bin/perl6
# print "Display = " + %*ENV{'DISPALY'} + "\n";
print "Perl Version = " + $*PERL + "\n";
</code>
$ ./env.pl6
Cannot resolve caller Numeric(Perl: ); none of these signatures match:
(Mu:U \v: *%_)
in block <unit> at ./env.pl6 line 3
What am I missing? I'd like to get the one I commented
out on line 2 working too. That gives me the following error:
Use of uninitialized value of type Any in numeric context
in block <unit> at ./env.pl6 line 2
Cannot convert string to number: base-10 number must begin with valid
digits or '.' in '⏏Display = ' (indicated by ⏏)
in block <unit> at ./env.pl6 line 2
Many thanks,
-T
