Hello Mohawk70,

thank you for sharing

It's a nice collection of formated date outputs and to me a clear study to learn from.

cheers ~ Vera

btw: there's a small mischief in your pasted code, as for a hard break of line 41(/42 )

Code: Select all

Macro LongMonth(theMonth)
  StringField("January February March April May June July August September October November
December",theMonth," ")
EndMacro

Code: Select all

Macro Weekday(theDate)
  DayOfWeek(theDate) + 1
EndMacro

This is totally wrong. DayOfWeek() returns 0-6, and you're adding 1 to it? Right now it's Friday here, but this macro says it's Saturday. And when it's Saturday (6), it's going to return 7, which has no day associated with it.

Hi C64,

well, you're right as for the DayOfWeek() command itself. But in this case +1 is needed because StringField() starts by 1 (not 0).

I only stumbled across this the other day, when building a formated date output myself.

Besides - when testing the lib it returns the correct weekdays for me - doesn't it for you ?

greetings ~ Vera

[C64]

Yes, you are correct. My bad.
