Note: The flag is set according to whether Omnis was able to make a call to this external command.
This command reads an entire file into a binary field. If you specify 'r' as the third parameter, it opens the file in read-only mode. It returns an error code, or zero if no error occurs. The returned binary value has the following format:
12 byte header containing the Type (4 bytes), Creator (4 bytes), and file length (4 bytes).
File data.
The Type is always ‘TEXT’, and the Creator is always ‘mdos’.
# Prompt the user for a file and read it's entire contents into the
# binary variable lBinFld
Do FileOps.$putfilename(lPathname,'Select a file','') Returns lReturnFlag
If lReturnFlag
Read entire file (lPathname,lBinfld) Returns lErrCode
End If
