Runabc is a graphical user interface to several command line driven programs for processing abc files. It is written in Tcl/Tk script and will run on any computer or operating system in which Tcl/Tk is installed. This includes Windows, Unix, Linux and Macintosh. The script now provides graphical user interfaces to abc2abc, abc2midi, abc2ps, abcm2ps and yaps. You also need a midi player and a postscript viewer. If you are running on Windows (2000, XP, Vista, Windows 7, Windows 8) or Linux. you can get many of the executables here and also from the web site The ABC Plus Homepage. For other systems you will probably need to download the sources and compile them yourself. The link below illustrates the operation of this program. The link install.html provides links to web sites where you can get the various components to run the program.

runabc.html describes what this program does. Updated 2018-02-07. You can also download the entire documentation in a zip file Updated 2018-02-07.

runabc.exe has Tcl/Tk built in for Windows users who do not wish to install Tcl/Tk 8.5 on their system. Runabc.exe is now created using tclkit ( First save it to your hard drive and then run (no installs).

runabcexe is a similar executable with Tcl/Tk builtin for Linux.

runabc.kit will run without tcl/tk on almost any system where tclkit has been installed. See install.html for details.

For Windows system, setup_runabc.exe will install runabc.exe and the abcMIDI executables, and create shortcuts on your start button and Desktop. Runabc will now work properly even if it is installed in the c:\Program Files (x86) folder. It will create a separate folder in your home folder called runabc_home where it will store runabc.ini and other files that it needs to write.

The Windows executable runabc.exe may return some strange error messages on Windows 10; for example
bad component "item": must be row or column while executing ".abc.titles.t identify item $locx [expr $locy+2]" (procedure "update_wholefile_and_toc" line 12)
In such situations I recommend installing the tcl/tk interpreter from www.activestate/activetcl. Download and install the community edition (ActiveTcl8.6.4.1....exe) for x86, not 64-bit. This should fix the problem with runabc.exe. Otherwise run the source code by clicking on runabc.tcl. is a new program under constant developed which is described on sourceforge. The source code here is unstable, but stable versions are available in the midiexplorer project on sourceforge.
