The attached worksheet, done in an earlier release, is a modified version from this site. There are other ways to do this, but this one works for me. You can alter the path info for file location that aligns with your particular system. This link is from the Maplesoft Application Center.

plotting data

Those Villanova worksheets are pretty old and somewhat outdated in general. In current Maple, you can easily plot a Matrix of 2-column data directly.

 C1:=<0,1,5,17>:
 C2:=<3,7,14,17>:
 plot(<C1|C2>);

Also, see ?ImportMatrix and ?ExcelTools[Import] and ?readdata for a few ways to read in data from a text file.

Sorry for not answering

Sorry for not answering earlier. Your suggestions works perfectly, both import from Excel and the readdata command. Thanks a lot!
