Development
System for Formula is a software that provides
instruments for fully exploiting Basic Line
Terminals by creating fully-structured and
personalized applications. In fact, thanks to DS
for Formula, it is possible to develop programs
for all the following basic line terminals: F630,
F660, F725, F732, F734, in both their standard or
"E" (Enhanced) versions.
DS for Formula uses a "C" standard ANSI
compiler, integrated with special libraries,
operating in an MS-DOS environment and developed
specifically for the type of terminals' processor.
Furthermore, the developed program is compatible
with any terminal model by recompiling the source
with specific libraries.
The libraries, developed by Datalogic, permit
direct management of the terminal's functions: for
example, the management of bar code reading
devices is immediate and rational thanks to
interaction with functions that automatically
start up the bar code acquisition procedure.
Equally transparent, by using a philosophy of
events programming, is the procedure for managing
the keyboard, display, serial and radio-frequency
communication, calendar/clock and, either directly
or through a vdisk utility, the data memory
organized into banks. The main hardware elements
generate a series of coded events that allow
Operating System multitasking to be effectively
managed.
All these functions are then grouped into a
structured application so as to manage the
terminal in the best manner possible.
Development System for Formula also offers a
series of effective general purpose application
examples which represent an excellent starting
point while simultaneously providing a practical
guide for studying and working on complex or
personalized programs.
