Operating Systems and
Programming Languages
PDTs generally have proprietary
operating systems installed even
though some manufacturers now
support
DOS or DOS like operating systems Ñprimarily to allow
programmers to develop in languages such as BASIC,
C, or PASCAL. At first glance, this may seem the best
choice, but for most data collection applications this
can be an overkill. Granted, the user must become familiar
with the manufacturerÕs programming language, however,
this is usually not very difficult and can often be
performed by a nontechnical individual. Proprietary
operating systems are designed specifically for data
collection applications and are generally quite efficient
when it comes to developing bar code applications.
The other alternative is to program the hand held
unit using a Resident Operating Program (ROP), if it
is supported by the manufacturer. The ROP is built-in
to the reader and allows the users to easily define
the data fields, the number of fields, the width of
each field, prompting messages, and record delimiters
of a file. The ROP is ordinarily flexible enough to
support most data collection applications.
