Thousand VB lines written in one click! You have FORTRAN programs and you wish to migrate or renovate them : we propose a very good tool for FORTRAN to Visual BASIC source code conversion. It manages to translate more than 90 % (in some cases 100 %) of FORTRAN commands into VB. The Fortran/VB converter translates: Declarations of variables, If, beginnings and ends of procedures, Do (several syntaxes), Write and print in a textual file, extractions of strings (nn:mm) etc. The new version 3 include a module to make changes in source files, as add or remove lines, count key words, change sentences, concatenate files, ... and a module to change date/hour on many files in one click.
