so far i have a program that can sucessfully read the protel schematic 
libraries , browse them and display them on the screen. i'm still 
tinkering with polygons as orcad doesn't know those.
still to be done arcs and rounded rectangles.

basically all pins , labels , lines and rectangles show up with correct 
data.for single part components

multipart components are a problem as this requires substantiallly more 
programming.( orced stores them in a different way and i need to do pin 
substitution ( orcad multiparts are all identical like in 4 gates in a 
package , every gate symbol holds the power and ground pin . protel 
doesn't every part van be completely different ) , or break the 
component into 4 subcomponents.

so i will takle those later.

i found some information on the orcad library format but not a lot.
who has the old orcad 386 book ( DOS version ) there used to be a 
chapter in there that described how to make schematic symbols.( some of 
us mght remeber the ascii drawings with the stars and stripes :-) ) 
 well there is a vector format.
i got some information but it is incomplete.

come on guys who got the specs ? i want to get this thing running by the 
weekend.

i will release sourcecode and executable here in the newsgroup ( visual 
basic 5.0 code )
