how to show a number in output text?

Hello group,

I'm learning to write a testbench so in part of the code I increment
a variable to count number of errors during simulation.

now, I need to know how I can print out a message showing number of
detected errors as following:

Found n error(s).

where n is the value in the counter variable.

Any help is appreciated.

p.s. I thought using & to concatenate would work but no

report "Found " & err_cnt & " error(s)" !!!! (wrong)
