Parsing Error "unrecognized token"

[AdjWang]

Hello,
I have tried to convert Voxel.pas here

but getting an error:

$ ./ptoc -in ../vxlseiii14x.r583/source/document/Voxel.pas
../vxlseiii14x.r583/source/document/Voxel.pas:1 11 error: unrecognized token:

I cloned ptoc to wsl and compiled it by make. My make version:

$ make -v

Thank you very much for all your help.

Kind regards,

This file has Dos/Win CR/LF convention and you are trying to convert it at Unix.
Please replace CR/LF with CR.
For example it can be done using dos2unix utility or zip:

zip voxel.zip Voxel.pas
unzip -a voxel.zip

Also please notice that it is Turbo Pascal file, so you need to specify -turbo option:

./ptoc -turbo -in ../vxlseiii14x.r583/source/document/Voxel.pas

It works! Thanks for your help!
