Syntax
ROMBANK
banknum section-name [,section-name,...]
•
Description
This directive declares which sections are allocated to the specified ROM
bank. The banknum specifies the ROM bank, ranging from 0 to the
maximum bank number of the destination microcontroller, according to
the directive .CHIP. The section-name is the name of the section defined
previously in the program . More than one section can be declared in a
bank as long as the total size of the sections does not exceed the bank size
of 8K words. If this directive is not declared, bank 0 is assumed and all
CODE sections defined in this program will be in bank 0. If a CODE
section is not declared in any ROM bank, then bank 0 is assumed.

code or data offset is relative to the beginning of the section where the
directive ORG is defined. The attribute of a section determines the actual
value of offset, absolute or relative.

Syntax
PUBLIC
name1 [,name2 [,...]]
EXTERN
name1:type [,name2:type [, ...]]
•
Description
The PUBLIC directive marks the variable or label specified by a name
that is available to other modules in the program. The EXTERN direc-
tive, on the other hand, defines an external variable, label or symbol of
the specified name and type. The type can be one of the four types: BYTE,
WORD and BIT (these three types are for data variables), and NEAR (a
label type and used by CALL or JMP).
