ZX80 sub string

[Shaun_B]

Hi guys,

I hear about a TL$ function on the ZX80 for string manipulation. Could anyone show me how this works please? Or do I need an upgraded ROM image to access it? (Currently emulating 4K ROM in EightyOne)

Many thanks,

Shaun.

Actually I worked it out:

Code: Select all

1 LET A$="HELLO MAGAZINE"
2 PRINT TL$(A$)

I just need an easy way to shuffle the string now.

Regards,

Shaun.

Hi,

Thanks for the really useful link.

I made a sort of scrolly text example in ZX80 BASIC - press enter on each static screen update to see the scrolly text one character at a time.

Enjoy!

Regards,

Shaun.
