MASM Balancer

This Applet will help you find out where in your MASM (Microsoft Assembler) Microsoft *.asm assembler program you have mismatched segment/ends macro/endm proc/endp or if/endif. It works by displaying your program in tidied form with coloured backgrounds that encode the nesting. By eyeballing the colours, you can quickly see anomalous patterns and find where the problem is.

It does not modify your original program in any way. You copy/paste a program, or a piece of a program, into this Applet/application hybrid then click Paste.

There is a program called BraceBalancer that does an analogous task for Java, C, C++, Pascal, Modula, CSS (Cascading Style Sheets) etc.

There is also a tidy program for MASM that aligns your code in four neat columns called MASMTidy.

1. Copy MASM source code with possibly unbalanced segment/ends, macro/endm, proc/endp or if/endif into the clipboard from your editor or IDE (Integrated Development Environment). In Windows use Ctrl-C.
2. Then click Paste to paste it into this program.
3. Anomalies in the background colours of the operators should help you quickly find the error.

Colours

• Bright yellow: you have more end markers than start markers, e.g. more endifs than ifs, in other words negative nesting. This is always an error.
• White: no nesting.
• Red: indicates struct-ends nesting. The lighter the red, the higher the level, i.e. not as deep nesting.
• Green: indicates macro-endm nesting. The lighter the green, the higher the level, i.e. not as deep nesting.
• Violet/blue indicates proc-end nesting. The lighter the violet, the higher the level, i.e. not as deep nesting.
• Grey indicates if-endif nesting. The lighter the grey, the higher the level, i.e. not as deep nesting.

When you select separate balancing you will also see | markers in the left margin to indicate nesting depth.

The MASMBalancer program works by marking up your program with HTML (Hypertext Markup Language). Java has quite a few bugs rendering HTML. You may notice lines improperly collapsed together. To view the marked up code accurately, use the export button, export to a *.html file and view it with your browser.

Java Requirements and Troubleshooting

MASMBalancer is a signed Java Applet (that can also be run as an application) to MASM Balancer. You are welcome to install it on your own website. If it does not work…

1. For this Applet hybrid to work, you must click grant/accept/always run on this site/I accept the risk to give it permission to allow MASMBalancer to accept data from the clipboard. If you refuse to grant permission, the program may crash with an inscrutable stack dump on the console complaining about AccessController.checkPermission.
2. In the Java Control Panel security tab, click Start ⇒ Control Panel ⇒ Programs ⇒ Java ⇒ Security, configure medium security to allow self-signed and vanilla unsigned applets to run. If medium is not available, or if Java security is blocking you from running the program, configure high security and add http://mindprod.com to the Exception Site List at the bottom of the security tab.
3. Often problems can be fixed simply by clicking the reload button on your browser.
4. Make sure you have both JavaScript and Java enabled in your browser.
5. Make sure the Java in your browser is enabled in the security tab of the Java Control panel. Click Start ⇒ Control Panel ⇒ Programs ⇒ Java ⇒ Security ⇒ Enable Java Content in the browser.
6. This signed Java Applet (that can also be run as an application) needs 32-bit or 64-bit Java 1.8 or later. For best results use the latest 1.8.0_131 Java.
7. You also need a recent browser.
8. It works under any operating system that supports Java e.g. W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32, W10-64, Linux, LinuxARM, LinuxX86, LinuxX64, Ubuntu, Solaris, SolarisSPARC, SolarisSPARC64, SolarisX86, SolarisX64 and OSX
9. You should see the Applet hybrid above looking much like this screenshot. If you don’t, the following hints should help you get it working:
10. Optionally, you may permanently install the Canadian Mind Products code-signing certificate so you don’t have to grant each time.
11. If the above Applet hybrid appears to freeze-up, click Alt-Esc repeatedly to check for any buried permission dialog box.
12. If you have certificate troubles, check the installed certificates and remove or update any obsolete or suspected defective certificates. The only certificate used by this program is mindprodcert2017rsa.cer.
13. Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
14. To ensure your Java is up to date, check with Wassup. First, download it and run it as an application independent of your browser, then run it online as an Applet to add the complication of your browser.
15. If the above Applet hybrid does not work, check the Java console for error messages.
16. If the above Applet hybrid does not work, you might have better luck with the downloadable version available below.
17. If you are using Mac OS X and would like an improved Look and Feel, download the QuaQua look & feel from randelshofer.ch/quaqua. UnZip the contained quaqua.jar and install it in ~/Library/Java/Extensions or one of the other ext dirs.
18. Upgrade to the latest version of Internet Explorer or another browser.
19. Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java.
20. Try upgrading to a more recent version of your browser, or try a different browser e.g. Firefox, SeaMonkey, IE or Avant.
21. If you still can’t get the program working click the red HELP button below for more detail.
22. If you can’t get the above Applet hybrid working after trying the advice above and from the red HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email at.
