1 The following pseudo operations are understood by LWASM.
|
|
|
2
|
|
|
3 SECTION <name>
|
|
|
4
|
|
|
5 This introduces a section called <name>. This is only valid if assembling to
|
|
|
6 an object file. Only one section can be open at any given time. Sections
|
|
|
7 may be ended with ENDSECTION. Only one section can be open at any given
|
|
|
8 time. A subsequent SECTION directive will end the previous section. It is
|
|
|
9 important to note that an end of file does not close the currently open
|
|
|
10 section. There cannot be a symbol on a SECTION line.
|
|
|
11
|
|
|
12 ENDSECTION
|
|
|
13
|
|
|
14 Specifies the end of a section. This is optional. There cannot be a symbol
|
|
|
15 on an ENDSECTION line.
|
|
|
16
|
|
|
17 ORG <addr>
|
|
|
18
|
|
|
19 Specifies the assembly address. For the raw target, this is advisory and
|
|
|
20 only affects the addresses of symbols. For the object file target, this can
|
|
|
21 only appear outside of all sections. For the DECB target, each ORG statement
|
|
|
22 after which any output is generated will generate a segment in the output
|
|
|
23 file. <addr> must be completely resolved during pass 1 of the assembly
|
|
|
24 process and thus may not refer to forward references or external symbols, or
|
|
|
25 other symbols that refer to such.
|
|
|
26
|
|
|
27 <symbol> EQU <value>
|
|
|
28
|
|
|
29 Makes <symbol> equivalent to <value>. <value> may be an external reference
|
|
|
30 in which case any references to <symbol> will also be external references.
|
|
|
31
|
|
|
32 EXPORT <symbol>[ as <name>]
|
|
|
33
|
|
|
34 Marks previously defined <symbol> for export. If <name> is specified, it
|
|
|
35 will be exported as <name>. <symbol> must not be an external reference and
|
|
|
36 must be defined before EXPORT.
|
|
|
37
|
|
|
38 EXTERN <symbol>[ as <name>]
|
|
|
39 IMPORT <symbol>[ as <name>]
|
|
|
40
|
|
|
41 Marks <symbol> as an external reference. If <name> is specified, <name> is
|
|
|
42 the local name the symbol is references as in this assembly file while
|
|
|
43 <symbol> is the actual symbol to be referenced externally.
|
|
|
44
|
|
|
45 END [<addr>]
|
|
|
46
|
|
|
47 Marks the end of the assembly process. Immediately terminates assembly
|
|
|
48 without processing any other lines in this file or any others. It is
|
|
|
49 optional. <addr> is only allowed for the DECB target in which case it
|
|
|
50 specifies the execution address. If it is not specified, the address
|
|
|
51 defaults to 0.
