. . . BROWSER SYSTEM OVERVIEW . . .
------------------------------------------------------------------------------
The BROWSER SYSTEM provides a fully mouseable browse utility for both DBFs
and arrays through the STDBrowse() function. Scroll bars are automatic and
menus are definable by the programmer. All functions required for movement,
data set control and refresh rates are provided.
NOTE:
The up/down status bar needs to know the current relative position within
the data set. The browser utility was designed to be RDD independant. To
accomplish this RDD independance the relative positioning function has been
separated from the main library and is addressed through the function called
IRecNo() (Index Record Number). The IRecNo() function performs two
jobs: The first returns the logical record position within the controlling
index and the second is to return the actual RECNO() of the logical record
number. A working example of this function to be used with the DBFNTX
driver for CA-Clipper 5.01 is included. (Look at the linking instructions.)
The CUA-Clip Library has a default IRecNo() stub function which is
replaced by your IRecNo() if you include it as a file in the link
process.
The included example utilizes functions written by Graham D. McKechnie of
RCM Software Pty. Ltd. and modified by Brian Marasca. The functions are
called NtxPos() and NtxRec(). (See IRecNo().)
