He doesn't seem to have appreciated the period of learning Basic. He says it was hard to read.
Maybe MSX BASIC specifically. I remember finding it annoying that whitespace would be altered as soon as I'd put in a line.
Then again, maybe he's never done C/C++
Full translation:
Er, I learned programming from the stuff called MSX BASIC, and the custom back then was that there were strange manners like when a FOR statement loops like this, the variable starts from I, and I somehow had the habit to name a variable using single character. It's easy... no, difficult to read, I admit.
