For the fifth statement:

 print -- "Date and Time:  ${(%):-%D{%Y-%m-%d %H:%M:%S %Z}} Test"

The following works:

print -- "Date and Time:  ${(%):-"%D{%Y-%m-%d %H:%M:%S %Z}"} Test"

Is this the correct interpretation of your statement, or did I somehow put
a bandaid on it.

I appreciate your input.

Thanks and best regards,

Jim
