![]() It seemed to be fading in popularity in the 90s but is now gaining popularity through several new dialects. It was popular in the 70s era of AI research. Lisp can lay claim to many programming language firsts, and can now be considered a family of languages as well as a language itself. log ( "Hello World!" ) LISPĭesigned a year after Fortran, Lisp is the second-oldest high-level programming language that’s still in common use. It was standardised under the name ECMAScript. JavaScript is what makes the web dynamic and interactive. Mainly because it is required to be in every web browser. JavaScript is the most commonly found programming language in the world. HelloWorld.java public class HelloWorld JAVASCRIPT (ECMASCRIPT) AOP is not popular but loved by some and its concepts do find their way into other languages and libraries. The de facto standard for the style of programming called Aspect Oriented Programming (AOP). It became the standard way of describing algorithms in academia for 30 years, meaning it influenced many other languages’ syntaxes, including C. Look at the documentation for your o/s if you are interested in them.A contemporary of the other early 1950’s programming languages FORTRAN, Lisp, and COBOL. ![]() There are other ways, outside Fortran, to tell the o/s to write to disk (or console or what have you) immediately. If you have a pre-2003 compiler then (a) for Backus' sake update and (b) it is likely that it supports a non-standard way to flush buffers if memory serves gfortran used to provide a subroutine which would be called something like call flush(6). ![]() I guessed that OP had unit 6 connected to stdout (aka *), since this is a near-universal default configuration, though not one guaranteed by the Fortran language standard. In its simplest form flush takes only one argument, the unit number of the output channel to be flushed. I guess that its buffering capabilities have some limits and if the program exceeded them the o/s would empty its buffers prior to program end.įortran now (since 2003 I think) provides a standard way of telling the o/s to actually flush the buffer to the output device - the flush statement. It is obvious (to me) from the situation OP describes that the output is being buffered, that is the program issues a write statement and passes the output off to the operating system which does as it damn well pleases - here it waits until the program ends before writing anything to the console. Insert it anywhere else you wish once you understand what it is doing. ![]() Insert the statement flush 6Īfter the first write statement to have its output sent immediately to the console. I saw a "similar" post earlier (can't find the link though, sorry about that) but it was not really what I was looking for. It happens that both of these messages get displayed only after the program is done running, not while the programs is executing.īut it keeps on doing the same thing. Specifically, the problem is that in the console, the first message should be shown immediately, "Program begins!", and after ~5 minutes it should show "Program ends!". The piece of the code I'm having trouble with is the following: subroutine main_program The code it self not that important, since it does what it has to do, but more the output generation. The problem comes when displaying text in the Eclipse console. I installed the "Photran" plugin to Eclipse, and have managed to compile everything perfect, and overall the program does what it has to do. I'm having a small difficulty with Fortran 90 and Eclipse. ![]()
