TEST—GETMAIN subcommand sperands

integer: specifies the number of bytes, in decimal form, of virtual storage to be obtained.
SP(integer) | SP(0): specifies the number of a subpool from which the virtual storage is to be obtained. If you omit this operand, the default value is subpool zero. The integer must be in the range 0 through 127.
EQUATE(name): specifies the address of acquired virtual storage is to be equated to the symbol specified by name and placed in the TEST internal symbol table.
LOC(BELOW): specifies the virtual and real storage area must be below 16 MB.
LOC(ANY): specifies the virtual storage area can be anywhere in the virtual storage addressing range. The actual location (above or below 16 MB) of the virtual storage area depends on the subpool specified. If the requested subpool is supported above 16 MB, GETMAIN allocates virtual storage above 16 MB, if possible.
LOC(RES): specifies the address of the virtual storage area depends upon the residence of the next instruction to be executed. If the instruction address in the PSW for the tested program is below 16 MB, the request is processed as LOC(BELOW). If the instruction address is above 16 MB, the request is processed as LOC(ANY). LOC(RES) is the default.
