> Of several jobs I've had in my 25 years, I've seen mostly
> Turbo/Image applications and one business application written
> entirely for KSAM. They all worked about the same. Instead
> of sever dozen The error recovery and maintenance methods
> were different, that's all. (Of course when KSAM went to
> Native Mode, error recovery improved.)

> On the surface, for an Image app, you see dozens of databases
> with dozens of datasets each. For an KSAM app, there are
> hundreds of individual KSAM files.
>
> For Image maintenance, you really need a tool like DBGeneral
> or Adager to resize files and rehash keys. For Native Mode
> KSAM I only needed MPEX to increase file size.
