Hello,

if i install the 6.17 version I have a problem for the strtolk opcode.
If I come back to the 6.16 version everything is ok.

Is something changed or it is it a bug?

On MacBook 2012 Catalina

Thank you

Check that Shex is  being produced correctly, the problem may be with the previous line.
