Well.. Couldn't the 4DOS shell simply just replace the DOS-0x21 vector with another one that checks for 0x4E or 0x4F, and redirect the calls to findfirst/findnext to a 4DOS-routine, and all other calls to the original DOS-vector? -- kennu@mits.mdata.fi <here's where the dumb quote is supposed to be>
