First Attempt

[Adrian Heathcote]

Hi All---well, my first attempt comprehensively failed. I made the 
changes suggested below (with one exception) and fontinst choked when it 
got to the T19 encoding which it claimed not to be able to find. 
(Lars---that one change that I didn't make: was this the spot that you 
thought should be changed to T1, or was it somewhere else?) Should I 
move to OT19 encoding for the old style figures? At a loss what to try 
next…

>>
>> \input fontinst.sty
>> \installfonts
>> \installfamily{T1}{pgj}{}

Should pgj really be pgjj in this case of old style figures?

Yes, this was the one suggestion that I was unsure about. Do you mean 
that T1 should really be t1? Or the T19s? I wasn't sure where the 
counting of the arguments started from. Also do I need the third of 
these lines?

(I think the documentation of Fontinst needs one or two more pages added 
to it.)

But a word processor like Word knows that there are differences there 
and can call them. How does it do it?

Anyway thanks for all the help.
