Why do I receive an error when I run the example code in the help documentation page titled "Using Dynamic Field Names"?

The example code in the help documentation page under "MATLAB -> Programming -> Data Types -> Structures -> Using Dynamic Field Names" seems to show that structures can have field names with spaces in them. However, when I try to create a structure with a dynamic field name that contains a space, I receive an error message:

str = 'Ann Lane';

x.(str) = 5;

 ??? Invalid field name: 'Ann Lane'.

This bug has been fixed in Release 14 Service Pack 2 (R14SP2). For previous releases, please read below for any possible workarounds:

We have verified that there is an error in the documentation for dynamic field names, in that the names of structure fields cannot have spaces. As a workaround, use 'Ann_Lane' and 'William_King' as the dynamic field names, instead of 'Ann Lane' and 'William King':

str = 'Ann_Lane';

x.(str) = 5;
