This is only valid if assembling to +an object file. Only one section can be open at any given time. Sections +may be ended with ENDSECTION. Only one section can be open at any given +time. A subsequent SECTION directive will end the previous section. It is +important to note that an end of file does not close the currently open +section. There cannot be a symbol on a SECTION line. + +ENDSECTION + +Specifies the end of a section. This is optional. There cannot be a symbol +on an ENDSECTION line. + +ORG <addr> + +Specifies the assembly address. For the raw target, this is advisory and +only affects the addresses of symbols. For the object file target, this can +only appear outside of all sections. For the DECB target, each ORG statement +after which any output is generated will generate a segment in the output +file. <addr> must be completely resolved during pass 1 of the assembly +process and thus may not refer to forward references or external symbols, or +other symbols that refer to such. + +<symbol> EQU <value> + +Makes <symbol> equivalent to <value>. <value> may be an external reference +in which case any references to <symbol> will also be external references. + +EXPORT <symbol>[ as <name>] + +Marks previously defined <symbol> for export. If <name> is specified, it +will be exported as <name>. <symbol> must not be an external reference and +must be defined before EXPORT. + +EXTERN <symbol>[ as <name>] +IMPORT <symbol>[ as <name>] + +Marks <symbol> as an external reference. If <name> is specified, <name> is +the local name the symbol is references as in this assembly file while +<symbol> is the actual symbol to be referenced externally. + +END [<addr>] + +Marks the end of the assembly process. Immediately terminates assembly +without processing any other lines in this file or any others. It is +optional. <addr> is only allowed for the DECB target in which case it +specifies the execution address. If it is not specified, the address +defaults to 0.
