3.2.5 FIND
The FIND command searches main memory, starting at address zero for a
page-aligned 128-Kbyte segment of good memory, or a restart parameter block
(RPB). If the command finds the segment or RPB, its address plus 512 is left
in Stack Pointer (SP) R14. If it does not find the segment or RPB, the console
issues an error message and preserves the contents of SP. If you do not specify
a qualifier, /RPB is assumed.
Format:
FIND [qualifier-list]
Qualifiers:
Command specific:
/MEMORY
Searches memory for a page-aligned block of good memory, 128K bytes in length. The
search looks only at memory that is deemed usable by the bitmap. This command
leaves the contents of memory unchanged.
/RPB Searches all physical memory for an RPB. The search does not use the bitmap to
qualify which pages are looked at. The command leaves the contents of memory
unchanged.
