The file could be an export file you should import with catimp or the file is transported with a ftp program as an ascii file it should be transported as a binary file.
There is first multi-axis drilling in V5R8 available feb. 2002 (very soon)but it´s posible to do some drilling operations with different axis in R7 but I have never really tested it.
Try to look under sequential in the online documentation.
The command under win NT or 2000 is "D:\Programmer\Dassault Systemes\B07\intel_a\code\bin\CNEXT.exe" -batch -e ExtractModelFromSequential
I don't think it is possible to save the approach and retract macros yet, but you can copy the operation from one part to another or put the operation into a catalog. With the catalog it is also possible to save a complete sequence of operations.
