Description

This is a numeric parameter (with valid values 0 or greater) that indicates the maximum amount of STBL space available to Janus SOAP Screen objects. Screen objects use STBL space and not FSCB space, and any instance of a Screen object must allocate the maximum allowable STBL space, even if some of this space may not be used by a particular application.

An application that exceeds its screen STBL allocation is cancelled, usually with a message like:

MSIR.0750: Class Screen, function AddField: no more space for screen field data ...

Some Sirius RKTools products, like SirScan and SirPro, also make use of Screen objects. The SCRNSTBL default value is sufficient for those products for Model 2 terminals. However, the default SCRNSTBL might not be sufficient for other terminal models, especially Model 4 or Model 6 terminals.

Note: The SCRNSTBL parameter affects the space allocated for Screen objects at compilation time. As such, increasing SCRNSTBL does not increase the amount of space available to pre-compiled requests unless those requests are re-compiled after resetting SCRNSTBL.
