Remark parameters are optional. They associate a description with the data consisting of up to 512 characters of text.
[ REMARK('text') | NOREMARK ]
equate abc a72f4. asid(1) length(80) area scalar +
remark('input params from EXEC statement')
Result: IPCS creates a symbol table entry for the symbol ABC. EQUATE associates the entry with an 80-byte area beginning at the absolute address, X‘A72F4’. The ASID(1) indicates that this address is in virtual storage and IPCS simulates dynamic address translation for ASID(1). AREA indicates that the symbol is neither a module nor a control block. SCALAR indicates that the symbol is a single block of storage, not an array. REMARK is your description of the 80-byte area.
equate abc+73 asid(1) length(80) area scalar +
noremark
Result: Assuming symbol, ABC, already exists in the symbol table, EQUATE overlays the new address and attributes for ABC but does not delete the existing remark.
