Clear_All()

created for Server support

Clear_Set()

created for Server support

Construct_Object()

Operation: CONSTRUCT_OBJECT Assumption(s): none Goal(s): define an instance with appropriate keys and properties Algorithm: relies on support module constructors Usage: used internally

Copy_Marked_Area()

Operation: COPY_MARKED_AREA Assumption(s): none Goal(s): copy marked text to ClipBoard Algorithm: sends CUT Usage:

Cut_Marked_Area()

Operation: CUT_MARKED_AREA Assumption(s): none Goal(s): cut marked text to ClipBoard object Algorithm: sends CUT Usage:

integerData_Field(integer item#)

created for EntItem simulation

integerData_File(integer item#)

created for EntItem simulation

Display()

created for Server support

End_Construct_Object()

Entry_Clear(integer ecflag)

created for EntItem simulation: ecflag <> 0 means use Cleared-array

Entry_Clear_All(integer ecaDoneFlag)

created for EntItem simulation: must clear if ecaDoneFlag = 0 OR if Data_File in DONE-array

Entry_Display(integer file# integer flag)

created for EntItem simulation and Server support: if file# = 0, display only if Data_File is in Done-array else display only if file# = Data_File

Entry_Update(integer file# integer flag)

created for EntItem simulation and Server support if file# = 0, display only if Data_File is in Done-array else display only if file# = Data_File

integerItem_Count()

created for EntItem simulation

Mark_Block()

Operation: MARK_BLOCK Assumption(s): none Goal(s): begin mark of text block in buffer Algorithm: sets COLUMN_MODE to False and sends MARK_ON Usage:

Mark_Column()

Operation: MARK_COLUMN Assumption(s): none Goal(s): mark columnar area of text in buffer Algorithm: sets COLUMN_MODE to True and sends MARK_ON Usage:

Mode_Insert()

Operation: MODE_INSERT Assumption(s): none Goal(s): set INSERT_MODE to True Algorithm: sets INSERT_MODE to True Usage:

Mode_Overwrite()

Operation: MODE_OVERWRITE Assumption(s): none Goal(s): set INSERT_MODE to False Algorithm: sets INSERT_MODE to False Usage:

Paste_Block()

Operation: PASTE_BLOCK Assumption(s): none Goal(s): insert text from ClipBoard into buffer at current position Algorithm: sends PASTE to ClipBoard object Usage:

Prompt()

Read_File()

msg for action_bar

Refresh(integer notifyMode)

Request_Clear()

created for FindEdit support

Request_Clear_All()

created for FindEdit support

Request_Delete()

created for FindEdit support

Request_Find(integer mode integer entUpdtFlag)

FindEdit support behavior

Request_Save()

created for FindEdit support

Request_Save_No_Clear()

this allows us to save a record without it clearing regardless of the Auto_Clear_DEO_State value

Request_Superfind(integer mode)

created for FindEdit support

set(integer item# integer newval)

Inherited from verify_mixin

created for EntItem simulation

set(integer item# integer newval)

Inherited from verify_mixin

created for EntItem simulation

Top_of_Panel()

created for Navigation support

Update_Dependent_Items()

Operation: UPDATE_DEPENDENT_ITEMS Assumption(s): none Goal(s): do nothing (cancels message sent by Server-mixin) Algorithm: none Usage:

IntegerValidate_Items(Boolean bNotFindReq)

created for server and EntItem support returns non-zero if data invalid, 0 if no error (valid) no action by default; intended for augmentation/override NOTE: if this object's validation fails, this object should take the focus.
