Switch Case and here-document redirection

I have some batch files using here-document redirection in switch case commands.

This used to work in v15 but fails in v20. I got v20 to work by extracting the case commands to a separate sub-routine.

Is this something that should be fixed in TCC or a (new) limitation of the switch statement?

Code:
@echo off

switch s
case s
   wc.exe << endinput
   1
   2
   3
   endinput
endswitch
This works in v15 but fails in v20.

Code:
@echo off

switch s
case s
   gosub runwc
endswitch
quit

:runwc
wc.exe << endinput
1
2
3
endinput
return
This works in both v15 and v20.

It will work better if you either

1. remove the whitespace before "endinput", or
2. use "<<-" instead of "<<"

But you are right. There was a change in behavior (between v16 and v17).

Thank you!

That did indeed fix the problems I had. Seems the whitespace before the end-marker confused the parser in the later versions.
