to Btrieve Interface function parameters.
Table 5-1
Function Executor Controls for Win16
Control
Description
File
Lists the full path of all open data files and displays the current open file. You
can move among open files, but you cannot open a file using this box. To open
a file, refer to “Opening a File”
This control corresponds with the Position Block parameter. Because each file
name represents a position block, a file name can appear more than once in
the list if the file has been opened more than once.
Transaction
Indicates whether the current operation occurs inside a transaction and the
type of transaction, as follows:
Exclusive – Exclusive transaction.
Concurrent – Concurrent transaction.
Conc+ModLk – Concurrent transaction with Modify Lock (+500) bias.
Operation
Current
Specifies the current operation code plus its bias (if any). The default is 0. If
you are familiar with Btrieve operation codes, you can enter the desired code.
Otherwise, use the List box to specify an operation. This control corresponds
with the Operation Code parameter.
Last
Displays the code of the last operation that was executed on the current file.
List
Lists all Btrieve operations and their codes. The default is Open (0). You can
move quickly through the list by entering the first letter of the operation you
want to perform.
