An often overlooked feature of LANSA is that up to EIGHT reports can be produced concurrently by any one program. Considering that often two or more programs are written to produce similar reports, (for example, one may be a detailed report, another may print selected details, and yet another may produce a summary), this is a significant feature.
If reports are usually produced together - and process basically the same information from the same files - then altering one of the programs to produce all reports concurrently can save both a lot of computer resource, AND simplify further maintenance of the reporting system.
