How CODE-1 Plus processes apartment information when presented as a single alpha character

Products Affected:  CODE-1 Plus
In releases prior to 4.0, if CODE-1 Plus found a single alpha character in an address line, the alpha character would be converted to an apartment and appended to the primary standardized output address in batch processing when using the INP or INPA option of SA OUT.

This has changed with the incorporation of address scan.  Address scan does a better job at identifying firm names overall, and this instance is one in which processing differs from pre-address scan (3.7) processing. The only way a single secondary value in a field by itself uniformly gets properly identified as an apartment is if the string is all numeric, which makes sense. An all-numeric is much more likely to be a secondary number than a firm name.
All alphas are more likely to be a firm name than a secondary, and are identified by address scan as such. In fact, all the values by themselves are returned as firm names whether they’re alpha OR numeric when the FIRMNM “U” parameter is supplied.
If the “#” character is put before the supposed secondary number, it’s always considered a secondary, and gets returned as a secondary unconditionally for a high rise address.
The suggestion is to put the “#” before the secondary string as the resolution.
