+ * This file contains the definition of the Third Eye Symbol Table.
+ *
+ * Symbols are assumed to be in 'encounter order' - i.e. the order that

+ * EXCEPT for globals! These are assumed to be bunched together,
+ * probably right after the last 'normal' symbol. Globals ARE sorted
+ * in ascending order.
+ *
+ * -----------------------------------------------------------------------
+ * A brief word about Third Eye naming/use conventions:
+ *
+ * All arrays and index's are 0 based.
+ * All "ifooMax" values are the highest legal value PLUS ONE. This makes
+ * them good for allocating arrays, etc. All checks are "ifoo < ifooMax".
+ *
+ * "isym" Index into the SYMbol table.
+ * "ipd" Index into the Procedure Descriptor array.
+ * "ifd" Index into the File Descriptor array.
+ * "iss" Index into String Space.
+ * "cb" Count of Bytes.
+ * "rgPd" array whose domain is "0..ipdMax-1" and RanGe is PDR.
+ * "rgFd" array whose domain is "0..ifdMax-1" and RanGe is FDR.
