The STOBK's for the high end of the virtual machine are "overlapped" into FRWRK to reduce page references. Changing FRWSTONM will control the number of STOBK's in FRWRK. Reducing this equate will reduce the number of STOBK's and increase the number of SUBBK's in the free list at the high end of this page. Increasing this equate will increase the number of STOBK's and reduce the number of SUBBK's. 0000004D FRWSTONM 77 Number of STOBK's in FRWRK 00000738 FRWSTOSP FRWSTONM*STOSIZEB Space in FRWRK for STOBK's DMSFRUMX Service Request Codes 00000000 FRWMXTLT 0 Return Total on unalloc queue < 16Mb 00000001 FRWMXLLT 1 Return Largest on unalloc queue < 16Mb 00000002 FRWMXTGT 2 Return Total on unalloc queue > 16Mb 00000003 FRWMXLGT 3 Return Largest on unalloc queue > 16Mb 00000004 FRWMXPLT 4 Return Total partial F.S. on a SUBBK < 16Mb 00000005 FRWMXPGT 5 Return Total partial F.S. on a SUBBK > 16Mb 00000006 FRWMXFLT 6 Return Num of full pages on a SUBBK < 16Mb 00000007 FRWMXFGT 7 Return Num of full pages on a SUBBK > 16Mb 00000007 FRWMXCOD 7 Equal to the last vaild code above.

They match the order of the SPLSUB array in the CMSSTOR macro. Updates to either one of these tables must be consistent. Whenever any of these subpools are specified on the CMSSTOR macro in the string form: SUBPOOL='NUCLEUS' a code byte will be generated in the plist that is an offset into this table. This will give immediate look-up of the SUBBK's for the preferred subpools. If a non-string form of the subpool name is given or it is not one of these subpools, the code byte will be zero - meaning don't use this look-up method but the "normal" path instead. The anchor for the GLOBAL subbk chain is placed in the zero slot of this table to "fill" it without having to waste 4-bytes of space.

The FRWBLSTK pointer, points to the next free BALR Save area available. The FRWBLLST field is used to determine if we are trying to get a Save Area beyond the maximum available. These Save Areas are managed by the DMSFRENT and DMSFREXT macros. IN THE EVENT THAT ALL SAVE AREAS BECOME FULL: When the BALR save stack becomes exhasuted, DMSFRMDI will be invoked. For the purpose of debugging, the registers of the caller to the routine that blew up will have been save in NUCON at FREESAVE. You can inspect: R11 = Address of FRWRK R13 = Address that was beyond the max BALR Save Area R14 = Address of the Caller R15 = Address of the Callee In addition, the last two characters of the Entry Point Name (or procedure) being invoked can be found at: FRWEPNAM in FRWRK and the module name at: FRWMONAM in FRWRK The audit trail of routines that were invoked to the point where all BALR Save areas became full can be accomplished by inspecting the R14 and R15 pairs in each of the Save Areas starting at FRWBLSV1. If it is determined that the solution to the problem is to add additional BALR Save Areas, please insure that they are added between the last one currently defined and the field: FRWENDBL as this is the field used to determine how many are available. Keep in mind that each BALR Save area added will take away space currently used for the SUBBK free list. This is not a critical problem as the worst that can happen is to cause the free list to acquire an extended page and perhaps fragment free storage a bit. If for some reason, you attempt to add BALR Save areas that extend this control block beyond 4096 bytes an assembly error will be generated as a protection mechanism. 08A8 2216 Address 4 FRWFRRRT Address of invoker of DMSFRRSV or DMSFRRBx 08AC 2220 Address 4 FRWFRORT Address of invoker of DMSFROSV or DMSFROBx 08B0 2224 Character 8 FRWMONAM Module name active if Save Stack exhausted 08B8 2232 Character 2 FRWEPNAM EP name active if Save Stack exhausted 08BA 2234 Bitstring 1 * (2) RESERVED FOR FUTURE IBM USE 08BC 2236 Signed 4 * (0) Insure proper alignment 08BC 2236 Address 4 FRWBLSTK Pointer to the next free BALR Save area 08C0 2240 Address 4 FRWBLLST Address of the last existing BALR Save Area BALR Save Area for Nesting Level 1 08C4 2244 Signed 4 FRWBLSV1 (16) BALR 1 Save Area for Callers regs 00000040 FRWBLSIZ *-FRWBLSV1 Size of one FRWRK BALR Save area BALR Save Area for Nesting Level 2 0904 2308 Signed 4 FRWBLSV2 (16) BALR 2 Save Area for Callers regs BALR Save Area for Nesting Level 3 0944 2372 Signed 4 FRWBLSV3 (16) BALR 3 Save Area for Callers regs BALR Save Area for Nesting Level 4 0984 2436 Signed 4 FRWBLSV4 (16) BALR 4 Save Area for Callers regs BALR Save Area for Nesting Level 5 09C4 2500 Signed 4 FRWBLSV5 (16) BALR 5 Save Area for Callers regs 00000A04 FRWENDBL *-FRWRK End of the DYNAMIC BALR Save Area Fixed BALR Save Area 1 Usage: Notes : Because this save area is used by DMSFRE, it must not be used by any routine callable from/in DMSFRO or DMSFRR except in the case of processing the ADDR= or SUBPOOL= parameters on OBTAIN as they are not supported via the DMSFRE interface.
