Info

The Assembler also recognizes a special constant that represents the assembly time location counter: "$" or "*". When "$" or "*" is used in an expression, the value taken is the location counter at the instant of assembly of the line containing the "$" or "*". Examples of Constants: 01010101B 17q $10 17777o "AB 567H %0110101 0ffffh '@ 13 7FFH $ * Examples of valid expressions: (start-end)>2 start minus end shifted right by two abc*5 'a!80h five times the value of abc ascii value of 'a' 0Red with 80 hex $+4 value of the location counter plus four *-3 value of the location counter minus three $FFFF
find any definition to satisfy the external reference, it will reserve a location in the bss segment segment of number of bytes. A label may appear in any number of comm directives. dc - Define Data Constant This directive has the form: [] dc[.l {,} where indicates an optional letter ("b", "W", or 11110) which indicates the size of the data object (byte, word, or long). The is an absolute or relocatable expression whose value is placed in the location. Multiple locations may be defined by a single dc directive by specifying multiple expressions separated by commas. Each expression will be evaluated and the resultant values will be placed in successive locations, each of which is assumed to be the size indicated by the size code letter. If the size code letter is omitted, the size is assumed to be the size of an integer (2 bytes). In the case of the dc directive it is permitted to have an expression of the form: '' where is one or more ASCII characters. The characters will be packed into successive bytes. ds - Define Data Storage This directive has the form: (] ds[.] where indicates an optional letter ("b","w",or "l") which indicates the size of the data object (byte, word, long). The indicates the number of data objects for which space is to be reserved. The number of bytes reserved is the multiplied by the size of the data object (1, 2, or 4 bytes). end - End of Assembly This directive has the form: end [] where [] is an optional label which, if specified, causes the output module's entry point to be set to that indicated by the label. The label should be an external label which must have been defined before the occurrence of the "end" directive. This directive is used to signal the end of input for the Assembler. equ - Equate Svmbal With A Value This directive has the form: {} equ {} The equ directive gives the value of the expression in the operand C.5.9
