CMD File: translate Windows error message

Is there a way to retrieve and display the text of a Windows error message inside of a CMD script?

For example, assume MYAPP.EXE returns 2 (ERROR_FILE_NOT_FOUND). The Windows error message associated with this is: "The system cannot find the file specified"

Can I retrieve and display that within my CMD script? For example,

REM mycmd.cmd
MYAPP.EXE
ECHO %ERRORMESSAGE%

Thanks.

FOR /f "delims=" %%a IN ('COPY /y "%sourcedir%\xyz" "%sourcedir%\pol" 2^>^&1') DO SET "copyresult=%%a"

ECHO %ERRORLEVEL% %copyresult%

Assuming the source file does not exist, then the error message should be redirected from device 2 (stderr) to device 1 (stdout) and hence be applied by the for to %%a and thence copyresult.

This produces errorlevel 1 for the copy case.

If you use a non-existent command like czopy in place of copy, then errorlevel will be 9009 but since the output is on two lines,

'CzOPY' is not recognized as an internal or external command,
operable program or batch file.

only the last is assigned to copyresult
