Hi JJ:

    Of course, I defined getobj() exactly  as you noted above, but failed to 
include its definition in my example.  I have used this for a few months 
now. It prevents a lot of typing errors for me.


    Because 1/2 of the time I work/develop in another C-based language (the 
Harbour language --- xHarbour), I make many mistakes when moving from 
Harbour to JavaScript several times a day.  So,  I created some utility 
string functions (inter alia)  for JS that emulate some those functions in 
Harbour:

    Here are a few below the starred line.

    I must say tho that I miss the '$' operator in Javascript.  In my 
harbour language,  it is implemented as follows:

        lFoundit := "MEL"  $  upper("isthatmelana##holeorwhat")     // 
looking for letters 'mel' in string
        // lFoundit returns true (or in harbour --- .T.)

        So, I use the function partof() below as a substitute

-Mel

cstr.substring(cstr.length-numchars,cstr.length) ;
