AMAP
Type
OMEGAMON Minor command
Description
Displays a map of virtual storage utilization within the private area. The AMAP minor command of PEEK displays a map of virtual storage utilization within the private area. This map indicates the maximum region available, the portion currently in use, and various areas within the region.
The AMAP display shows all virtual storage, or you can limit the map to storage above or below the 16M line by appending an A or B argument as shown.

Area descriptions for storage above the 16M line:
- Highest 31-bit address
- The highest possible address in 31-bit architecture.
- Top of extended private
- Highest address within the extended private area.
- ELSQA/SWA unallocated
- The amount of storage not currently allocated within the extended system area.
- Fragmented free space
- The amount of free storage within allocated pages of the extended system area.
- Current bottom of ELSQA/SWA
- Lowest address allocated within the extended private area for the extended system area.
- Avail. for ELSQA/SWA only
- The amount of unallocated storage between the current bottom of the extended system area and the limit of the extended user area.
- Extended User Area Limit
- Highest address possible for the extended user area.
- Avail. for ELSQA/SWA/USER
- The amount of unallocated storage between the extended user area limit and the current top of extended user area. Note that the extended system area can allocate storage within this area.
- Current Top of Ext. User Area
- The highest address currently allocated within the extended private area for the extended user area.
- Largest free block
- The largest contiguous piece of unallocated storage within the extended user area.
- Extended User unallocated
- The amount of storage not allocated within the extended user area.
- Fragmented free space
- The amount of free storage within allocated pages of the extended user area.
- Bottom of Extended Private
- The lowest address currently allocated within the extended private area for the extended user area.
Area descriptions for storage below the 16M line:
- Highest 24-bit address
- The highest possible address in 24-bit architecture.
- Top of Private
- Highest address below the common area (start of CSA).
- LSQA/SWA unallocated
- Total of contiguous 4K areas. The numbers include LSQA, SWA and subpools 229/230.
- Fragmented free space
- Total of areas within LSQA which are each less than the 4K available for allocation as defined by FQEs.
- Current bottom of LSQA/SWA
- Lowest address allocated to LSQA/SWA subpools.
- Avail. for LSQA/SWA only
- Total space available for LSQA/SWA allocation. This includes the LSQA/SWA unallocated value and the amount of space in the region available area.
- User Area Limit
- Highest address available for user allocation (region size plus IEALIMIT).
- Avail. for LSQA/SWA/USER
- Amount of space available for problem program allocations, not including unallocated areas within the region used.
- Current top of User Area
- Highest address currently allocated for problem program use.
- Largest free block
- Largest contiguous area available within the region used.
- User unallocated
- Total of the contiguous 4K areas within the region used which are available for problem program use.
- Bottom of Private
- Lowest address within the private area (above the resident nucleus rounded up to the next 64K boundary).
- Prefixed Storage Area
- Fixed storage location starting with absolute zero.
