Go4IT Alight's static code analysis delivers a big value in application modernization initiatives by offering:
It has been a while since we started working with our first COBOL programs, struggling to extract as much information as possible from them and trying to understand the differences between the dialects from each of the vendors. A lot of time since we started developing our technology agnostic compiler, diagraming tools...
Our colleagues from the blog Hacker Rank have developed this interesting article about the existing gap between the current demand for COBOL experts and the number of COBOL programmers that are available. In our opinion, using tools such as Go4IT Alight helps bridging this gap by providing novel programmers a means to understand COBOL and flatten their learning curve.
During the discovery Go4IT Alight extracts all the knowledge from the source code of the analyzed legacy programs. This process is similar to the one done by compilers, yet reaching a higher level of knowledge. In the first place, Alight discovers the structure of the analyzed source code, identifying variables, functions and classes. Then the behaviour of each function is analyzed. Finally, the discovery process extracts information about the data model used by the programs (i.e.
Alight analysis algorithms are capable of obtaining valuable information from the source code. This information in often crucial to fulfil a successful modernization, as they identify problems in the program structure, performance, etc. of the legacy applications, and thus, corrections can be applied before transforming the application to a newer technology. Currently, Alight has many analysis tools available to all programing languages:
The last two phases of an Alight modernization are devoted to obtaining a functional replica of the original application in a newer technology. The first of these two aims at preparing the source code for the new platform: the optimization phase.
Alight uses powerful generation engines that allow us to link pivot language models with modern programing languages, such as Java, Shell script, HTML, Javascript or Python among others. Furthermore, Alight can regenerate the code in the original language, which is a useful feature to implement automated code correctors (for example, automated elimination of GOTO statements in COBOL).
