Operation
Assembly symbols are made global via the GLOBAL assembler directive, see Section
information. linker-defined symbols act like EQU directives, however they are defined by the linker
during the link process, and no definition for them will appear in any source or intermediate file.
labels. The name of the label will be the C identifier with a leading underscore character. The
linker-defined symbols include symbols used to mark the bounds of psects. See Section 3.13.3. The
symbols used to mark the base address of each functions’ auto and parameter block are also shown.
Although these symbols are used to represent the local autos and parameters of a function, they
themselves must be globally accessible to allow each calling function to load their contents. The
C auto and parameter variable identifiers are local symbols that only have scope in the function in
which they are defined.
has been assigned. There is no information encoded into a symbol to indicate whether it represents
code or variables, nor in which memory space it resides.
with a psect as is the case with absolute C variables. Linker-defined symbols showing this as the
psect name may be symbols that have never been used throughout the program, or relate to symbols
that are not directly associated with a psect.
formation on generating these files.) These differ to that shown in the map file in that they list
all symbols, whether they be of global or local scope, and they only list the symbols used in the
module(s) associated with that list file.
5.9 Operation
A command to the linker takes the following form:
Options is zero or more linker options, each of which modifies the behaviour of the linker in some
way. Files is one or more object files, and zero or more library names. The options recognised by
the linker are listed in Table

In earlier versions of HI-TECH C the linker was called LINK.EXE
Non-static C functions, and non-auto and non-static C variables directly map to assembly
Each symbol is shown with the psect in which they are placed, and the address which the symbol
If the psect of a symbol is shown as (abs), this implies that the symbol is not directly associated
