@Brian Woodward what happens when you do TCC /... What do the DEBUG dialog boxes indicate? Joe

_conpty returns 1, so TCC is running in a Windows pseudoconsole (ConPTY) Joe

It would appear he is running it from C:\WINDOWS\system32\cmd.exe which is what _parent returns. Joe

Hopefully @rconn will find what you have reported helpful in resolving the issue. I note that you are not running TCC elevated, and are not running TCC as admin. As a test, see if you get the same delay when running TCC elevated and as admin. Joe

To see if something in your TCMD.INI file is causing a problem, start TCC with the /I option, which signals TCC to not load the .INI file, execute TCSTART or TCEXIT, or load plugins. Ref: TCC Startup Options Ref: _ININAME TCC internal variable Run TCCInfo.btm, available from this link...

Please review, and see if these are of any help. Ref: Excluding TCC from Microsoft Defender anti-Virus scans Ref: Running TCC.EXE on the GPU Joe

When you invoke the C# compiler, csc.exe must be loaded and initialized for each compilation. Windows may keep some of its files in the system cache, and it may create a Prefetch entry, but neither is guaranteed. However, csc.exe also supports a shared compiler process. For example: csc...

Thanks, that works. I could not infer that from the help file, but I have added the info to my personal TCCHelp file. Joe

I'm not asking you to support TCC/LE. I'm not asking you to support 4DOS. I'm asking for a clearer error message when the PLUGIN command in TCC v36 attempts to load a 32-bit TCC plugin. This is not a clear error message; U:\>plugin /l FileUtils-x86.dll TCC: (Sys) The specified module could not...

For now, my work around is to avoid the pipe completely, and let PowerShell do everything itself. R:\>pshell /s "$s = Get-Content -Raw r:\lines.txt; $s -split '\r?\n' | chomp 4" Line Line Line Joe
