Syntax: recordname RECORD field [, field]...
See also: STRUCT, MASK, WIDTH, OPTION EXPR16/EXPR32,
Control-Flow Directives
Description:
Declares a record template of one or more specified bit fields
but does not allocate storage for the template. Separate multiple
fields with a comma.
Records can be used as constants or expressions. They are treated
as a BYTE or WORD with 16-bit expressions and as a BYTE, WORD, or
DWORD with 32-bit expressions. The sum of the widths for all fields
must not exceed the expression width.
Once a record template is declared, you can use it to define
record variables or constants, in which each field not initialized
assumes the default value. Records are defined with the following
syntaxes:
[name1] recordname {[initializer1] [, initializer2]...}
[name1] recordname <[initializer1] [, initializer2]...>
Use of <recordname> is similar to the other variable definition
directives (such as BYTE and WORD). Curly braces or angle brackets
are required even if no initializers are given.
If a record constant appears as part of an expression in a control
flow directive (such as .IF or .WHILE), you must use curly braces
instead of angle brackets to enclose the fields.
The assembler will treat the name of a record field without the
MASK or WIDTH operators as the bit number of the first bit of the
record field.
Parameter Description
recordname A unique symbolic name.
field Each field is in the form
fieldname:width[= expression]
where <width> is a constant giving the width of the
field (in bits) and <expression> optionally sets an
initial or default value.
