CTL. Fourth Generation Language
CTL is a programming language that allows you to develop any application quickly and safely. By its design, CTL gives rise to very powerful and easy-to-maintain programs, with a reduced number of lines.
Programs written with CTL are 100% portable between UNIX / Linux, Windows, local area networks, etc. CTL guarantees the writing of a single source code portable to any hardware platform.
CTL is a non-procedural, structured and recursive language that extends a complete set of a 3GL standard language incorporating all the usual flow control instructions.
In addition to the characteristics that we usually find in other 3G languages such as parameters, variables or arrays, CTL has a series of specific objects aimed at enhancing programming tasks such as FORMS, FRAMES, STREAMS, CURSORS or MENUS.
CTL incorporates all the power of SQL embedded in its syntax in the same way that it provides an effective interface for accessing operating system functions.
CTL has a program debugger that allows us to locate any error precisely in the shortest possible time.
It provides us with a wide set of functions already defined and with high execution speed, as well as more than 100 instructions that are classified into the following groups: Flow control; input, output and assignment; of FORM; from FRAME; STREAMS and interface with SQL.
