The following tables provide a complete list of one-byte and extended p-code instructions. Each instruction is represented by a specific hexadecimal number. For example, LDCW2 is in the row marked “60” and the column marked “1” or “9.” Thus, it has a value of 61 hexadecimal. LDCW5 is in the same column but one row down, so it has a value of 69 hexadecimal.
The syntax for p-code instruction names is described in Chapter 3, “Reducing Program Size with P-Code.” The p-code opcodes are fully described in the Help file PCODE.HLP.
