I've been asked to add some enhancements to a workbook designed several years
ago by someone else. In addition to the enhancement I've beed asked to
design, I'd like to clean up code, converting macros to VBA routines,
functions, etc. The current workbook is about twenty-eight megabytes and
takes considerable time to load. There are about fifty worksheets in the
workbook. Any suggestions on how I might improve load time?
