Because you can put 22H (SHLD) in a DATA statement but not a string:
65531 DATA m-98&"lkj3
will work just fine. As long as the quote doesn't appear first, READ A$
will read the whole thing. And SHLD is a very useful opcode. You just
can't use 2CH (comma) which is opcode INR L, a bit less useful than SHLD
I think.

Yes, it can, but you have to execute the code up there for the
assignments to occur first. I tested it last night. But I also
discovered DATA statements work better in those lines.

Hey John,
Correct, 65530 is listable but cannot be created interactively.
But want to hear something really cool? Using the VirtualT
Memory Editor, I created a BASIC program with not just one,
but TWO lines numbered 65531! And BASIC ran both lines
correctly without complaint. This means you could have any
amout of hidden ML code you want that doesn't require the
special work-around, other than avoiding 00H.
Using TS-DOS and Emulated NADSBox in VirtualT, I was even
able to save, kill and re-load this BASIC program with no issues.

Hey John,
Very interesting. It looks like the range is actually
65531-65536 that are invisible. They don't even show up
with a full program edit. You can't GOTO or GOSUB to
them, but you can put "65529 REM" and then GOSUB 65529.
Then BASIC will execute the invisible lines. Very
nice! Then you could safely emed ANY ML in strings
within those lines it appears.
Haha. Bitchin’ :-)
So I guess line 65530 is listable you just can’t create a
line 65530 interactively?
