[Ham-Mac] Running Excel 97 "application" on Mac

[Chuck Counselman]

At <http://www.qsl.net/ac6la/xlzizl.html#Details> you'll find an 
awesome Excel 97 "application" called "XLZIZL" for modeling 
transmission lines and matching networks, or "antenna tuners."

I'd like to run XLZIZL via Excel 98 on my Mac PowerBook G3 with OS 
9.1.  (Although I have Virtual PC 5.0.3 with Windoze 98, I don't have 
Excel 97 for Windoze.)

Excel 98 (Mac) opens/executes many Excel 97 (Windoze) worksheets with 
no problem; but when I used Excel 98 (Mac) to open <XLZIZL.xls>, I 
got an error message saying "Microsoft Visual Basic Compile error: 
Can't find project or library."

In my Microsoft Office 98:Office folder are files named <Visual Basic 
for Applications>, <VBA Converter (1.0)>, <VBA Extensibility Library 
(1)>, and <VBA Localization Library (1)>, and <VBA Object Library 
(1)>.

I need a clue about Microsoft Visual Basic.  What library is missing? 
Is it something that's available for Windoze but not Mac?
