For one, our software (1.5MByte, 30Klines) uses (sub-)class Pen heavily. However, if their motivation to remove Pen is be that vector-graphics is platform-dependent (e.g. native window support for color-pen drawings), then I can "sort-of" understand it. Still, Pen as an example-Class should remain. Or, keep it as a fileIn for backward- compatibility.... wait, I already have said that many times and it seems to have the opposite effect :-( By the way, how is Digitalk treating you guys with respect to new releases and backward-compatibility of Smalltalk-V? -- --------------------------------------------- P.S. van der Meulen, MS 02 prls!pieter PRLS, Signetics div. of NAPC ----------- 811 E.Arques Avenue, Sunnyvale, CA 94088-3409
