Good evening Dennis,
I believe you need to add the following link command to your file
link datefns
either before or after your procedure definition.
In addition, the procedure julian() requires a date_rec and not a list
of values
The following works correctly
procedure main()
out1 := julian(date_rec(2017, 5, 25))
write(out1)
end
link datefns
with the result of
2457899
However, I would also suggest that you include the following call
initdate()
before calling any of the procedures available in datefns.icn
regards
Bruce Rennie
