***** Begin Revision History *****

1	-----	-----	ADD SYNOW FIELD TO THE STATEMENT DESCRIPTIONS
			SO THAT CERTIAN STATEMENTS CAN HAVE THEIR
			"SYNTAX" EXECUTED BEFORE THE CALL TO THEIR
			SEMANTICS

2	242	15010	CONTINUE IS A VALID SUBSTATEMENT OF A LOGICAL IF

***** Begin Version 6 *****

3	1044	EGM	20-Jan-81	20-15467
	Define a new error action code (fatal statement out of order)
	and place it in the statement order transition table at the proper
	point.

***** Begin Version 7 *****

4	1201	DCE	19-JUN-80	-----
	Add new keywords - CHARACTER, ELSE, ENDIF, THEN, INQUIRE, INTRINSIC,
	SAVE.

5       1214    CKS      8-May-81
        Add statement description block for block IF, remove THEN statement.
        Remove TERMBAD from ENDIF statement so it is allowed to terminate a DO.

6	1247	CKS	6-Aug-81
	Add SUBASSIGN statement

7	1456	CKS	11-Jan-82
	Add IOINPUT flag to READ, ACCEPT, REREAD statements.  This bit is
	needed so EXPRESS can know whether to call NAMREF or NAMSET when it
	sees a name in an IO list.  This flag shoves over the SYNTX field
	to bit 27, so this field is now only 9 bits long.

8	1464	RVM	26-Jan-82
	Connect the entry for the INTRINSIC statement with its BNF.

9	1466	CDM	1-Feb-82
	Connect the entry for the SAVE statement with its BNF.

1527	CKS	9-Apr-82
	Modify the statement order requirements for PARAMETER statements.
	PARAMETER may now appear before IMPLICIT, between IMPLICIT and
	specification, or after specification statements.

1536	CKS	19-May-82
	Allow DATA statements to be freely mixed with type specification
	statements and PARAMETER statements.

1556	CKS	14-Jun-82
	Allow ENTRY statements anyplace FORMAT statements are.  (Ie, anyplace.)

1573	CKS	1-Jul-82
	Add statement description blocks for END DO and DO WHILE.

1610	CKS	5-Aug-82
	Allow NAMELIST statements anyplace after the IMPLICITs.  (Like DATA.)

1621	CKS	24-Aug-82
	1556 caused labels on ENTRY statements to be marked as FORMAT statement
	labels, because LABDEF trickily checks the order code to decide if a
	statement is a FORMAT or not.  Add an order code ENTR for entry
	statements, identical to FORMAT but with a different number so LABDEF
	won't freak out.

1665	CKS	8-Nov-82
	Allow GOTO as the last statement in a DO loop.  We catch non-computed
	GOTOs in the semantic routine.

1677	CKS	16-Nov-82
	Set IOINPUT for DECODE to prohibit expressions in its IO list.

***** End Revision History *****

***** Begin Version 11 *****

4502	MEM	22-Jan-85
	Changed size of hash table in CLASHASH from 130 to 154 and reordered
	entires of external routines and entries of routine descriptions.
	This was done because adding the entrys for the DELETE, REWRITE and
	UNLOCK statements would cause there to be more than 2 levels of
	collisions. With the new ordering there are no collisions.
	Descriptions of GLOBSTA and PROTSTA were removed since they don't exist
	Add entry for routine DELESTA.	

4503	MEM	22-Jan-85
	Add entry for routine REWRSTA.

4504	MEM	22-Jan-85
	Modify entry for routine UNLOSTA so it can be used by both UNLOAD and
	UNLOCK.

4530	MEM	17-Feb-86
	Add long symbol support: Add underline as legal fortran character.
