Re: VAriables on the command line.

[Harry Binswanger hb@xxxxxxxx]

I understand that {240} means "contains." But not what  does. I
even understand that VA@01 contains the text in sg01. Why does ".1" do the
lopping off? Or does it?


It's new in Xy4--a string slicer, sort of. Suppose you have this string
stored in s/g 01


aaaaa-bbb-cccccccccccccccc-d-eee

Then

 returns aaaaa
 returns bbb
 returns cccccccccccccccc

and so on.

Here's a little program to demonstrate. Use XYDEC on it:
'%--_XYENCode_start--
~',*','^~',*',
'^~',*','^~~>',*','^'FF'BC~'._
~',*','^~',*','^~~+1
~>',*','^~<6~>~~',*','^~~'^

'%--_XYENCode___end--


Carl, you are holding a programming clinic here, so I don't feel too bad
asking beginner's questions . . .

It all works as designed, including the blink-of-an-eye Wally Bass derived
decode. Question: why the commas B,X . . . Q,2 executing the tyf/nv
portion? A requirement of XM (which also reads x,m,)? For the n'th time,
thanks Carl.
