FlagShip compiler & development
[edit]
FlagShip [1] is a programming and development tool from multisoft[2]. Like all other compilers, it is primarily designed for professional software development. However, thanks to its simple interface, it is also often used by semi-professional and experienced users who want to create a database program with minimal effort. Due to its full Clipper (programming language) compatibility, FlagShip is also ideally suited for porting existing DOS applications to Unix, Linux, or the MS Windows operating systems.
There's no learning curve if you're familiar with xBase dialects such as dBase, FoxBase, FoxPro, Clipper and Visual Objects. This is the case for millions of trained software developers who have been using one of these 4GL languages for years; they can all switch directly to FlagShip. If you have no previous knowledge of xBase but have experience in programming of C, C++, Java, Pascal, Delphi, Basic, etc., the learning curve is very flat you can create your first program in less than 10 commands.
Visual FlagShip automatically creates a GUI-oriented and/or textual program from the same source code. Of course, the appearance can be freely modified, both using the OOP classes and the corresponding functions. The execution mode (GUI, textual, or stream for the web) is automatically determined by the environment in a heterogeneous application, or can be specified by input parameters during compilation or program execution.
For example, with these few program lines, saved in the text file address.prg
USE address ALIAS adr SHARED NEW
SET COLOR TO "W+/B,GR+/R,W/B,W/B,GR+/BG"
SET GUICOLOR OFF
cls
@ 1, 0 SAY "Id No. " GET adr->IdNum PICT "999999" VALID IdNum > 0
@ 3, 0 SAY "Company" GET adr->Company
@ 3,35 SAY "Branch" GET adr->Branch WHEN !empty(adr->Company)
@ 4, 0 SAY "Name " GET adr->Name VALID !empty(adr->Name)
@ 4,35 SAY "First " GET adr->First
@ 6, 0 SAY "Country" GET adr->Country PICTURE "!" + repli("x",24)
@ 8, 0 SAY "Zip " GET adr->Zip PICT "@!" VALID !empty(adr->Zip)
@ 9, 0 SAY "City " GET adr->City
@ 10, 0 SAY "Street " GET adr->Street
@ 6,35,11.4,47 GET adr->Type RADIOGROUP {"Male","Female","Company","None"}
@ 7,50 GET adr->Interest CHECKBOX CAPTION "Interested party"
@ 8,50 GET adr->Customer CHECKBOX CAPTION "Customer"
@ 9,50 GET adr->Reseller CHECKBOX CAPTION "Reseller"
@ 10,50 GET adr->Distrib CHECKBOX CAPTION "Distributor"
READ
"address.exe" or "./address"
as "address.exe -io=t"
... and invoking
FlagShip address.prg -o address
... is the program compiled into an executable (here address.exe in the Windows environment or ./address in Linux). Execute by name like any other application.
