- * probably right after the last 'normal' symbol. Globals ARE sorted

- * 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.
