Some Peculiarities of Macaulay under MPW

• While Macaulay is active, files cannot be saved in the normal way. Instead, one must save a file (corresponding to the contents of a window) by closing that window - just click in the close box at the upper right hand corner. Then select "Open" from the file menu and reopen the window to go back to work. It is sometimes important to do this, because if Macaulay crashes the contents of windows that have been put there since the last save will be lost. (Note that the Worksheet cannot be closed, and thus it cannot be saved while Macaulay is running.) An option is of course to quit Macaulay (type exit or command-.), save the file in the usual way, and then restart Macaulay in the Worksheet and get back to where you were by selecting all of the window you are working from and typing <enter>.
• Output from Macaulay will appear wherever the cursor is in the Worksheet. Thus to be sure that output appears at the end of the Worksheet, after moving the cursor by clicking elsewhere within the Worksheet, it is necessary to click at the end of the Worksheet.
