GLOBALV - Release Notes, Version 3.0       (Dated 18/09/98).

Version 3.0 of GLOBALV is now available. This is a 'new function' release.

New function

Prior to Version 3.0, if the IRXFUSER function package containing GLOBALV was reloaded (for whatever reason), all information regarding the global variables was lost. This was due to the fact that, the control block for managing the GLOBALV Dataspace, was held within the GLOBALV module.

Version 3.0 of GLOBALV maintains all control information for the Dataspace within the Dataspace itself. This means that GLOBALV variables persist across any reloading of IRXFUSER.

New features  

The following functions have been added :-

ADD parameter - (same as SET parameter)

PURGEALL parameter - This will purge ALL defined GLOBALV pools.

DEBUG parameter - Displays module details and Dataspace debugging information.

Maintenance changes 

1. ABEND0C4 when defining variable within 3 bytes of the end of the Dataspace area. This problem has now been fixed.

2. Users were unable to use all 2Mb of Dataspace area within first 'pool'. This problem was due to the hardware restriction on certain processors, whereby, Dataspaces start at an origin of 4K not zero. Due to the restructuring of the Dataspace at Version 3.0, this problem has been fixed.

3. The maximum number of 'pools' that can be defined has been reduced from 256 to 255.

Software requirements

The minimum software pre-requisite is now MVS/ESA 4.2.2
