There may have been some delays and problems in the router feeding the postings from Finland so I shall repost my recent messages.

This is not quite what you are looking for, but you might be interested in the linear programming and linear goal programming solver /pc/ts/tslin24.arc, which can be obtained by anynymous ftp from 128.214.12.3. (It has also appeared in comp.binaries.ibm.pc.) To anticipate a question, the source code is not available.

At least when I am doing so. >Why is that? Now I do not know why it is so, but what you should do is to check for the IOResult yourself in your program at reset or rewrite time: FileMode := 0; {to allow testing even protected files} {I-} reset(myfile); {I+} result := IOResult; If the result = 152 then the drive is not ready. Simple as that. (Tested with a Turbo 5.0 program). ...................................................................
