Tried out the 20 beta. I use @REGEXSUB heavily in my batch files and it is not functioning properly.

Simplified example:
echo %@REGEXSUB[1,"^TCC ([0-9]+)",TCC 2]
In 17.00.77 x64, this returns "2". In 20beta it returns an empty string.

I suppose this could have broken in 18 or 19, but given the change of regular expression library in 20 I think it's more likely that it's a regression in the beta.

Interesting. Thanks for checking. Perhaps there's something odd about my environment, or it's a 64-bit specific issue.

Just tried again (I uninstalled 20 but kept the files zipped up in case I wanted to run another test).

[c:\tt]ver & echo %@REGEXSUB[1,"^TCC ([0-9]+)",TCC 2]
