I'm not sure what you want, but something like this might be helpful:
use [Weekdays Index] [
Weekdays: system/locale/weekdays
forall Weekdays [
Index: index? Weekdays system/locale/weekdays
do reduce [
to set-word! join first Weekdays "?" 'func [
"Is Date this weekday?" Date [date!]
]
reduce ['= Index 'Date/weekday]
]
]
]
which produces this:
>> source Wednesday?
Wednesday?: func [
"Is Date this weekday?" Date [date!]
][= 3 Date/weekday]
and is used like:
>> Wednesday? 13/Mar/2002
== true
