Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi,

just encountered trailing chars in date$() and time$() functions. E.g.

print time$(now) returns "19:28:07 0" and
print date$(now) returns "17-03-21 0"

datetime$ seems to be not affected.

This bug(?) applies to Pico and PicoWeb, both latest versions.

Reagrds,
Gerald

Hi Gerald,

I think "now" is interpreted as a regular variable.

I.e. you get the result of Date$ plus the variable "now", which in your case is "0".
Try your entries after "Option explicit".

thanks twofingers,

you are absolutely right. Overlooked that there are no arguments with that functions. Retrospectively I would have expected a syntax error, but be it as it is.

tnx agn,
Gerald

This illustrates one of the problems with parsing expressions.

Date$ is a valid function that returns the date.  (now) is a perfectly OK (if odd) expression which resolves to the variable now which defaults to zero.  Put the two together and you have a completely correct BASIC expression which does not do what you expected.
