Ha ha, yes I thought myself a little crazy when I started writing this series last year so I am glad you are enjoying it! Yes, you can use GET to grab the ASCII number of the character, I just find it easier to use the STRING so that's what I went with. You might also notice I haven't used the PSION II MENU instruction, works great on the II but the updated version on the 3 is not good so I decided to just ignore it ;-)

@@HandheldComputing Indeed :) i only recently got a Psion II LZ from England. I had one when i was a teenager and it got lost somewhere along the way. I think the cool thing about OPL is that you have simple access to a (admittedly very simple) data base. One can imagine the huge amount of boiler-plate code needed to do something halfway as simple using Java for example. You could probably write similar stuff using a bash script with a couple of sed commands, of course. I also recently bought a slide rule, because i never used one at school (we were already badgering our parents to get us Casio fx7000g's). It's interesting to think that the slide rule i got was made in 1970, so there are 18 years between it and the Psion organiser. then there are 35 years between the psion organiser and 2023---almost twice as long. Apart from constant connectivity not much has fundamentally changed in those 35 years.

@@EdouardTavinor Yes, OPL is a very simple language with easier syntax than Java. So maybe not as powerful but I think pretty much anyone could use OPL and a you say its relatively easy to read/write to a data file via OPL making it perfect for keeping and maintaining data. I guess slide rules were probably considered high tech when they 1st came out too. Sometimes simple functionality is the best way!

So pleased people are enjoying these videos, I was a little worried it would fall on deaf ears! I have loved learning to program OPL and hope it shows! Oooohhh a 200LX, very nice this is something missing form my collection.... for the moment...

I recently bought a couple of rechargable 9v batteries that can be charged through a USB cable. We live in a time of wonders :) they work in my psion LZ

I'm glad you enjoyed it, does seem a little silly making this video series when its already 30+ years out of date lol

Yes I saw a review of these on @bigclivedotcom they look good!

Ожидается видео Palm Pilot. Что касается качества видео на этом конкретном видео, у меня были серьезные проблемы с фокусом!!! Так что извините за это, я в конечном итоге переснял его 4 раза, в любом случае проблема исправлена, поэтому следующая должна выглядеть лучше :-)

@@HandheldComputing спасибо что ответили. Подписался на ваш канал, снимайте всё что интересно я обязательно всё посмотрю. Тема карманных ПК очень интересная, раньше с умом подходили к проектированию интерфейсов. Сейчас в интерфейсах надо делать слишком много кликов чтобы добраться до цели и это удручает.
