In 8085 Instruction set LHLD is a mnemonic that stands for Load HL pair using Direct addressing from memory location whose 16-bit address is denoted as a16. So the previous content of HL register pair will get updated with the new 16-bits value. As HL pair has to be updated, so data comes from two consecutive memory locations starting at the address a16 and also from next address location. This instruction uses absolute addressing mode for specifying the data in the instruction. It occupies 3-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes LHLD Address 2A ... Read More

In 8085 Instruction set, SHLD is a mnemonic, which stands for Store HLpair using Direct addressing in memory location whose 16-bit address is denoted as a16. As HL pair has to be stored, so it has to be stored in two consecutive locations starting at the address a16. We know that H and L are 8-bit registers. So their contents will be stored in two consecutive memory locations as each memory location can hold 8-bits of data. This instruction uses absolute addressing mode for specifying the destination. It occupies 3-Bytes in the memory. Mnemonics, Operand Opcode(in HEX) Bytes ... Read More

In 8085 Instruction set, ADD R is a mnemonic that stands for “Add contents of R to Accumulator”. As addition is a binary operation, so it requires two operands to be operated on. So input operands will reside on Accumulator and R registers and after addition the result will be stored back on to Accumulator. In this case, “R” stands for any of the following registers or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M It is 1-Byte instruction so occupies only 1-Byte in memory. As R can ... Read More

Use UNION if you want to select rows one after the other from several tables or several sets of rows from a single table all as a single result set. Let us see an example. Creating first table mysql> create table UnionDemo1 -> ( -> id int -> ); Query OK, 0 rows affected (0.59 sec) Inserting records into first table. mysql> insert into UnionDemo1 values(1), (4), (10); Query OK, ...

You can handle it by creating an array and insert an object into Array. Bapisdhd1 order_header_in = new Bapisdhd1(); order_header_in.DocType = "OR"; order_header_in.CollectNo = "111022"; order_header_in.SalesOrg = "11011"; order_header_in.DistrChan = "100"; order_header_in.Division = "000"; order_header_in.DlvBlock = "010"; order_header_in.PurchNoC = "TEST ORDER"; newOrder.OrderHeaderIn = order_header_in;
