acl_delete_symbol

	status.i4.v = acl_delete_symbol(symbol_name.i1a.r)

	This routine deletes a symbol created by an Accelerator Command
	Language (ACL) command.  If a null pointer is passed for the symbol
	name, all symbols will be deleted.  These symbol values still exist
	after the ACL file has finished executing to determine reading or
	status values resulting from the execution.

	symbol_name	null terminated symbol name
			(If a value of NULL is passed for this argument,
			 all symbols will be deleted.)

	This function returns ACNET status values as follows:

	OK			success
	CLIB_NO_SUCH		symbol doesn't exist
	CLIB_NOTENB		current symbol table belongs to compiled
				code and cannot be deleted
	otherwise		other ACNET format error code

	This function requires the following include files:

	ul_acl_h:acl_h, acnet_errors_h
