COBOLd

Fix your COBOL programs automatically with the power of genetic programming.

Demo

• Install a COBOL compiler:

sudo apt-get install open-cobol

• Install GenProg

• Clone this repository:

git clone https://github.com/squaresLab/COBOLd.git

• Compile limit.c in the src directory, naming the binary limit

cd COBOLd/src
gcc -o limit limit.c

• Then cd to the bug you'd like to repair and run GenProg using the configuration file included with the bug:

cd COBOLd/code/zunebug
/path/to/genprog-code/src/repair configuration

It may take a few runs (the search is stochastic, after all!), but if GenProg finds a repair it will report repair found, and output the repaired version of the program to a repair subdirectory.
