ERASE and COPY FILE are two new commands in Guineu.
ERASE supports the RECYCLE clause to move files into the recycle bin. I haven't it tested on platforms other than Windows desktops yet. Guineu supports ERASE ?, as well as the undocumented ERASE "". Both let the user interactively choose a file.
COPY FILE copies files. SET SAFETY is not yet supported. If the destination file exists it is overwritten. There might be some scenarios that do not yet work the same as in VFP. COPY FILE in Guineu does not work on embedded files.
