DATA command, did I find a bug or a feature

Hallo allemaal,

I'm busy writing my own OS and BASIC meant to run on my Commodore PC20-III and written in ML. Checking the behavior of DATA and READ on my C64 I ran into this:

1 data 1,2,
2 data 3,4
3 read a,b,c,d
4 print a,b,c,d
run
1    2    0    3

Notice the sole comma at the end of line 1. I more or less expected an error during the run because no data can be found after that comma but you can see the result. I thought to be smart and to run this little program on an IBM 5150 but with the same result. Then it struck that CBM BASIC was written by Microsoft as well. And I don't have other machines (or even an emulator) at hand where I could test this.

My question: did I run into a bug or is this supposed to happen?


With kind regards / met vriendelijke groet, Ruud Baltissen
