Currently SQL VARCHAR() scalar function under DB2 for i supports lengths of up to 32k or 32k-1 w/Nullable values. HLL on IBM i support 64k Varchar column/fields as well as 16MB Varchar lengths. Other Platforms (Microsoft) also support much longer lengths (2Gb).
Using a high-level Language such as RPG IV, developers have the ability to retrieve data from Web sources, such as Watson/IBM Cloud and store that information. While fixed-length fields support very long data results, the SQL VARCHAR function and column attribute supports only 32k. This length is "old" and should be increased to at least 64k but I would prefer 16MB or even 2GB to be compatible with other platforms.
