.field value [,size]

Initialize a bitfield of

size

bits in the current section. If

value

is relocatable, then

size

must

be 16.

size

defaults to 16 bits. If

value

does not fit into

size

bits, the value will be truncated.

Successive

.field

directives will pack starting at the current word, filling the most significant

bits first, and aligning to the start of the next word if the field size does not fit into the space

remaining in the current word. A

.align

directive with an operand of 1 will force the next

.field

directive to begin packing into a new word. If a label is used, it points to the word that

contains the specified field.

.global symbol [,...,symbol_n]

.def symbol [,...,symbol_n]

.ref symbol [,...,symbol_n]

.def

nominally identifies a symbol defined in the current file and availalbe to other files.

.ref

identifies a symbol used in the current file but defined elsewhere. Both map to the standard

.global

directive.

.half value [,...,value_n]

.uhalf value [,...,value_n]

.short value [,...,value_n]

.ushort value [,...,value_n]

.int value [,...,value_n]

.uint value [,...,value_n]

.word value [,...,value_n]

.uword value [,...,value_n]

Place one or more values into consecutive words of the current section. If a label is used, it points

to the word allocated for the first value encountered.

.label symbol

Define a special

symbol

to refer to the load time address of the current section program counter.

.length

.width

Set the page length and width of the output listing file. Ignored.

.list

.nolist

Control whether the source listing is printed. Ignored.

.long value [,...,value_n]

.ulong value [,...,value_n]

.xlong value [,...,value_n]

Place one or more 32 bit values into consecutive words in the current section. The most signif 

icant word is stored first.

.long

and

.ulong

align the result on a longword boundary;

xlong

does not.

.loop [count]

.break [condition]

.endloop

Repeatedly assemble a block of code.

.loop

begins the block, and

.endloop

marks its termi 

nation.

count

defaults to 1024, and indicates the number of times the block should be repeated.
