MASM Usage 2-20 Example 1 $RES 5 The operation field consists of one subfield ($RES) and is a valid MASM directive. Example 2 A $EQU 2 The operation field consists of one subfield ($EQU) and is a valid MASM directive. Example 3 APROC,1,2 The operation field consists of three subfields. Subfield 1 is a user-defined procedure. Subfields 2 and 3 are objects which the procedure can refer to. Example 4 LA,U The operation field consists of two subfields. Subfield 1 may be an instruction mnemonic. Subfield 2 is operand information to be used when generating the instruction. Example 5 + 14 The operation field is void. 2.3.3.3. Operand Field The operand field of a MASM statement can contain multiple fields. It is part of the functional portion of a MASM statement. The operand begins with the first nonblank character after the operation field (or label field if the operation field is a void) and continues until the end of the functional portion of the statement. The operand can consist of more than one field, or it can be a void. 7830 8269-001
7830 8269-001 MASM Usage It is not necessary for the operand field to contain the maximum number of subfields implied by the operation field. When omitting a subfield other than the normal first field or last field, the construct comma-zero-comma (,0,) or two contiguous commas (,,) is necessary. If the last subfield is omitted, a comma is not required after the last coded subfield. Any subfield referenced but not specified in the operand is evaluated to zero. Any subfield of any field of the operand portion can be flagged by prefixing the subfield with an asterisk (*). An asterisk cannot stand alone in a subfield, although *0 is acceptable. Example 1 A $EQU 2 The operand consists of a single field, the value 2. Example 2 APROC ABC,*0 The operand consists of a single field with two subfields. The first subfield is the symbol ABC. The second subfield is a flagged item with the value zero. Example 3 LA,U A0, TAG The operand consists of a single field with two subfields. The first subfield is the symbol A0, and the second subfield is the symbol TAG. The leading space in the second subfield is ignored. Example 4 APROC APPLE TREE The operand consists of two fields. Field 1 is the symbol APPLE, and field 2 is the symbol TREE. Example 5 APROC APPLE,,02 The operand consists of a single field with the following subfields: The symbol APPLE A void subfield that evaluates to zero The value two 2-21
