- * If the area does not yet exist then a new area
- * structure is created and linked to any existing
- * linked area structures. The area flags are copied
- * into the area flag variable. For each occurence of
- * an A directive an areax structure is created and
- * linked to the areax structures associated with this
- * area. The size of this area section is placed into
- * the areax structure. The flag value for all subsequent
- * area definitions for the same area are compared and
- * flagged as an error if they are not identical.
- * The areax structure created for every occurence of
- * an A directive is loaded with a pointer to the base
- * area structure and a pointer to the associated
- * head structure. And finally, a pointer to this

- *
- * ABS/CON - All sections (each individual areax
- * section) are concatenated with the
- * first section starting at the base
- * area address. The size of the area
- * is the sum of the section sizes.
- *
- * NOTE: Multiple absolute (ABS) areas are
- * never concatenated with each other,
- * thus absolute area A and absolute area
- * B will overlay each other if they begin
- * at the same location (the default is
- * always address 0 for absolute areas).

- * REL/OVR - All sections (each individual areax
- * section) starts at the identical base
- * area address overlaying all other
- * areax sections for this area. The
- * size of the area is largest of the area
- * sections.
- *
- * REL/CON - All sections (each individual areax
- * section) are concatenated with the
- * first section starting at the base
- * area address. The size of the area
- * is the sum of the section sizes.
- *
- * NOTE: Relocatable (REL) areas ae always concatenated
- * with each other, thus relocatable area B
- * (defined after area A) will follow
- * relocatable area A independent of the
- * starting address of area A. Within a
- * specific area each areax section may be
- * overlayed or concatenated with other
- * areax sections.
- *
- *
- * If a base address for an area is specified then the
- * area will start at that address. Any relocatable
- * areas defined subsequently will be concatenated to the
- * previous relocatable area if it does not have a base

- * presented to the linker. At the end of the first pass the setbase(),
- * lnkarea(), setgbl(), and symdef() functions are called to evaluate
- * the base address terms, link all areas, define global variables,
- * and look for undefined symbols. Following these routines a linker
- * map file may be produced and the linker output files may be opened.
- * The second pass through the .rel files will output the linked data
- * in one of the four supported formats.

- * Ascii S1 - Data Record
- * Ascii S9 - End of File Record
- *
- * Record Length Field - This field specifies the record length

- * length value is converted to two ascii
- * characters, high digit first.
- *
- * Load Address Field - This field consists of the four ascii

- * order is as follows:
- *
- * High digit of high byte of address.

- * High digit of low byte of address.
- * Low digit of low byte of address.
- *
- * In an End of File record this field con-

+
+/*)Function VOID newarea()
+ *
+ * The function newarea() creates and/or modifies area
+ * and areax structures for each A directive read from
+ * the .rel file(s). The function lkparea() is called
+ * to find the area structure associated with this name.
+ * If the area does not yet exist then a new area
+ * structure is created and linked to any existing
+ * linked area structures. The area flags are copied
+ * into the area flag variable. For each occurence of
+ * an A directive an areax structure is created and
+ * linked to the areax structures associated with this
+ * area. The size of this area section is placed into
+ * the areax structure. The flag value for all subsequent
+ * area definitions for the same area are compared and
+ * flagged as an error if they are not identical.
+ * The areax structure created for every occurence of
+ * an A directive is loaded with a pointer to the base
+ * area structure and a pointer to the associated
+ * head structure. And finally, a pointer to this
+ * areax structure is loaded into the list of areax
+ * structures in the head structure. Refer to lkdata.c
+ * for details of the structures and their linkage.
+ *
+ * local variables:
+ * areax **halp pointer to an array of pointers

+ * ABS/OVR - All sections (each individual areax
+ * section) starts at the identical base
+ * area address overlaying all other
+ * areax sections for this area. The
+ * size of the area is largest of the area
+ * sections.
+ *
+ * ABS/CON - All sections (each individual areax
+ * section) are concatenated with the
+ * first section starting at the base
+ * area address. The size of the area
+ * is the sum of the section sizes.
+ *
+ * NOTE: Multiple absolute (ABS) areas are
+ * never concatenated with each other,
+ * thus absolute area A and absolute area
+ * B will overlay each other if they begin
+ * at the same location (the default is
+ * always address 0 for absolute areas).
+ *
+ * REL/OVR - All sections (each individual areax
+ * section) starts at the identical base
+ * area address overlaying all other
+ * areax sections for this area. The
+ * size of the area is largest of the area
+ * sections.
+ *
+ * REL/CON - All sections (each individual areax
+ * section) are concatenated with the
+ * first section starting at the base
+ * area address. The size of the area
+ * is the sum of the section sizes.
+ *
+ * NOTE: Relocatable (REL) areas are always concatenated
+ * with each other, thus relocatable area B
+ * (defined after area A) will follow
+ * relocatable area A independent of the
+ * starting address of area A. Within a
+ * specific area each areax section may be
+ * overlayed or concatenated with other
+ * areax sections.
+ *
+ *
+ * If a base address for an area is specified then the
+ * area will start at that address. Any relocatable
+ * areas defined subsequently will be concatenated to the
+ * previous relocatable area if it does not have a base
