The Command Line As A String - HP -28S Manual

The Command Line as a String
The text that you key into the command line is equivalent to the con-
tents of a string object-that is, a sequence of characters. You can
programmatically execute a command line by entering the text in a
string and executing STR- (string-to-objects). This technique is useful
for storing programs in text form, which is more compact than object
form. Also, any local names that exist when STR- is executed will be
recognized in the command line.
