How to suppress message of validatestring?

z = validatestring( 'azaa', {'aaa','bbb'} );

outputs in red to the Command Window

Expected input to match one of these strings:

'aaa', 'bbb'

The input, 'azaa', did not match any of the valid strings.

Is there a way to suppress this message?

I would like to get this information in an output argument and take control over the presentation.

I reckon it's straight forward to make my own version of validatestring and shadow the factory version.

validatestring() is mostly a whole lot of throw(), so if you do not want the message, put in a catch

Thanks! Of course, time for me to take a break.

No, break exits a for or while loop. You want to go outside and play a game of catch :)
