Delila programs are used to analyze DNA sequences and to make Sequence Logos and Sequence Walkers.

The Delila programs are written in the language Pascal, so to run them you would either need a binary or you have to compile the source code.

Binaries for Delila Programs

Since I work on a Sun Microsystems computer, the only kind of binary I can supply is for that computer. When I generate the web page for a program, the binaries for Sun4 Sparc computers are automatically stored.

For historical reasons the Delila programs were written in Pascal because it was the best language available at the time. It is a good language for teaching and as a consequence it is quite good for building solid logic.

Because I use the original Jensen and Wirth definition of Pascal, any good, standard native Pascal compiler should compile the Delila programs. Originally the programs were compiled on Vax and CDC Pascal compilers with no problems.

1. The Sun Microsystems Compiler WORKS WELL but HAS BEEN ABANDONED.

2. Using p2c to translate, and gcc to compile the C versions
   under Unix WORKS WELL.

3. The GNU Pascal Compiler (gpc) is a great way to transport these programs. As of the latest release GPC will now work on Delila Programs! THIS WORKS WELL. as of 2000 July 24.

WARNING: Free Pascal or any other Borland Turbo Pascal based compiler will NOT WORK with Delila programs. That compiler does not understand file pointers and the get() and put() functions, which are part of the original Jensen and Wirth Pascal. Unfortunately these compilers do not follow the ISO standard.

• Other Pascal Links: lists several free compilers.

• More Pascal Links: lists several free compilers too.

Executables and libraries need to be installed properly for each machine, which is generally no problem for the Windows machines. Data files, i.e., postscript, should be transferred as ascii types. Many people forget this detail.
