I see, fine.

Err... well, I meant 'Phil' was the value of a string variable.
I thought this would be clear.

Ok, then, if I got this right, you have to do
 write(num_var:1) and write(string_var)
for output without spaces, whereas
 write(num_var)   and write(string_var:1)
both don't work this way.

This seems a bit inconsistent and confusing to me.
I see that your programs rely on this way, but my programs rely on BP's
way, and I don't think there's anything worse with BP's way than the
standard's way. So, obviously, gpc needs to support both ways.

This explains to me why this clipping is needed in standard Pascal.
However, I really don't want to use hand-made strings in my programs,
I really could stand a little more comfort... :-)
