I am working with GNUCobol cobc version 3.2.0

It seems that COPYBOOKS do not work during the compile step? The source code is going through the esqlOC precompiler first. I have these to lines

  COPY RCDC00   
  COPY screenio.cpy

in my source code and neither copybook is found

I have both COBCPY and COB_COPY_DIR environment variables set in my _make.bat file
SET drv=C:
SET apphome=%drv%EOS

  SET "COB_COPY_DIR=%apphome%cobcpy"
  SET "COBCPY=%apphome%cobcpy"

I’ve tried with and without double quotes. I’ve even tried putting my copybook names in the environment variable like this
SET “COB_COPY_DIR=%apphome%cobcpyRCDC00.cpy”
SET “COBCPY=%apphome%cobcpyRCDC00.cpy”

I tried putting the full path inside my cobol program at column 8 as
COPY C:EOScobcpyRCDC00.cpy

  COPY C:EOScobcpyRCDC00.cpy.

 COPY "C:EOScobcpyRCDC00.cpy"

I am familiar with Microfocus and so, I might be blinded to GNUCobol syntax?
