2003-6-30: Fixed bugs in dialog_event that cut off name of event item at 4 characters, and prevented selection of fertilizer item. Fertilizer events can now either use a selected item or an entered fertilizer amount in the form "(183N18.3P)".
2003-4-2: Added "-s" parameter option to call of CENTURY version 4. Parameter is optional in some compile dates but required in others (including the October 1998 version currently downloadable from Colorado State).

New fields in table [Output Annual]: "som1c(1)", "som1c(2)", "som2c", "som3c".
2001-7-20: Fixed bug in dialog_event that caused crash when viewing an event of certain types. SQL "WHERE" clause entry added to output chart dialog. This allows you to enter a where clause directly for selecting records to chart, i.e. "Rotation = 1 AND Tillage = 1". Control list view improved to reduce corrupted image display.
