Spell/400 is a spell-checking tool from Black and Blue Software Ltd for IBM i / AS/400 / iSeries / i5. It focuses on traditional green-screen applications and 5250 GUI environments. Rather than being a general-purpose IDE plugin, its goal is to add PC-style spell-checking capabilities directly into existing enterprise business screens.
In terms of functionality, Spell/400 can check text in any application and interact with users through pop-up dialogs. The page emphasizes that it can be embedded into existing screens with a single command or API, and can even overlay spell checking where source code cannot be modified. This is valuable for IBM i legacy systems with high maintenance costs. It also provides Auto Correct, Auto Learn, and Quick Correct, allowing it to automatically handle common misspellings, abbreviation mistakes, and typing errors, while displaying and fixing multiple errors on a screen at once.
For languages and dictionaries, the product offers nearly 30 dictionaries covering English variants, formal language, foreign languages, and names. It also supports IBM or BNB dictionaries, and can extract vocabulary from database fields to build company-specific dictionaries. Its integration ecosystem is centered on IBM i, with explicit compatibility for IBM WebFacing and other 5250 GUI tools. For auditing, it can record who used spell checking, what they did, and the surrounding context, while also providing controls at the user or application level.
The page does not disclose pricing, licensing model, payment methods, or whether the product is open source or offers a self-hosted option. On the documentation side, there are downloads, learning resources, an evaluation guide, and runnable examples, but the public content lacks an API reference, installation requirements, version compatibility matrix, and deployment instructions. Buyers still need to contact the vendor for confirmation before procurement.
Its strengths are its very clear positioning: it addresses text-entry quality issues in traditional IBM i business systems while also covering dictionaries, auditing, and permission controls. Its weaknesses are its narrow scope and incomplete public information. It is best suited for enterprise development, maintenance, and compliance teams that still rely heavily on AS/400, IBM i, 5250 green screens, or WebFacing.
The page does not provide information on access from China, mirrors, payment options, or local support, so real-world network connectivity is unknown. If access or procurement is restricted, alternatives could include localized custom development within the IBM i ecosystem, embedding spell checking during 5250 front-end modernization, or using general-purpose spell-checking components in surrounding web-based systems.
