PerTable 1.1 A Periodic Table Editor PerTable allows you to design and print your own periodic chart. It can print a table so large that the print job would use 1000 sheets of paper. It can also print a poster of a single element in color. To install, copy all of the files in PERTABLE.ZIP (except VBSOURCE.ZIP) to a diskette. From Windows File Manager select SETUP.EXE. PerTable requires that VBRUN300.DLL be in your windows\system directory. That file is available on the internet at cica.indiana.edu/pub/pc/win3/util (get VBRUN301.EXE). VSAFE may need to be removed for the setup program to work. For example, a message that the Windows system directory can't be written to is caused by VSAFE. (VSAFE Tip: VSAFE warns when a program has been changed. Unfortunately, the update option is only available from DOS, not Windows. To update the program, click the DOS Prompt icon and run the program from DOS. Your program will advise you that Windows is already running, and will end. But before that, VSAFE will beep and let you select update.) The source code for this program is in VBSOURCE.ZIP. Unless you are interested in programing, I would delete that file. The program was written using Visual Basic 3.0 for Windows. To run the source code in the Visual Basic programing environment, copy PERTABLE.HLP and PERTABLE.DAT to the directory containing the source files. The program will give a load error because it does not know which directory PERTABLE.ICO is in. To correct this, go to the frmPeriodic Properties Window, choose icon, and find PERTABLE.ICO in the file dialog box. When printing with a laser printer, the option "Print Truetype as Graphics" MUST be selected. Otherwise, letters will be missing and extra pages may be printed. This update corrects a column heading problem: There were two group 1A's and no group 1B for two of the Old Style Column Heading options.
