154 * is used to detect the end of the mnemonic/directive
155 * list in xxxpst.c, and a value which is normally

175 * preceeding the next normal symbol. The structure also
176 * contains the symbol's name, type (USER or NEW), flag

178 * to the area structure defining where the symbol is
179 * located, a reference number assigned by outgsd() in

210 * will be linked to this structure through the structure
211 * element 'struct area *a_ep'. The structure contains the
212 * area name, area reference number ("_CODE" is 0) determined
213 * by the order of .area directives, area size determined
214 * from the total code and/or data in an area, area fuzz is
215 * an variable used to track pass to pass changes in the
216 * area size caused by variable length instruction formats,
217 * and area flags which specify the area's relocation type.
