1 The following sample programs correspond to the Product Launch presentation files located at The samples have been reformatted to eliminate word wrapping, and for easier cut-and-paste into a ProvideX session. A few of the programs require the data file smndata, which is included with the Object Oriented Programming presentation files. MEM1 0010!
