StrToNum is broken?

[Rincewind]

I have some code to check the sub-version number of the installed Java by stipping the number from the end of the install path (retrieved from the registry). However, the StrToNum function is returning zero. Here is the code:

    STRING	szJavaHome, szJavaDir, szJavaVer;
    NUMBER	nJavaVer;
    BOOL  	bGoodJava;
  if (StrLength(szJavaHome) > 1) then
    if (ParsePath(szJavaDir,szJavaHome,FILENAME) = 0) then
      if (StrSub(szJavaVer,szJavaDir,StrFind(szJavaDir,'_')+1,2) = 0) then
        if (StrToNum(nJavaVer,szJavaVer) = 0) then
          if (nJavaVer >= 26) then
            bGoodJava = TRUE;
          endif;
        endif;
      endif;	
    endif;
    SprintfBox(INFORMATION,"","%s\n%s\n%s\n%ld",szJavaHome,szJavaDir,szJavaVer,nJavaVer);

The result is:
C:\Program Files (x86)\Java\jdk1.6.0_26
jdk1.6.0_26
26
0

Obviously, the StrToNum function is failing, but I can't tell why.

StrSub doesn't return 0 for success, so maybe the inner StrToNum just isn't being called?

Oops, teach me to read the documentation.
Guess that should be >0.
Thanks Robert.
