Hi there Peter I have been writing Smalltalk since 1990 first with Digitalk and then IBM/Instantiations VAST. However, I am a newbie with Pharo having only used it for the last 3 weeks so I am pleased to have got my first Seaside app working successfully - it’s a home banking management app that imports from Sage compatible CSV files supplied by NatWest. This is the only real difficulty so I am very pleased with the work.
I use my own brand key/value database that saves objects out to the disk. With my new M1 MacBookAir, I am getting read and write values around .3 second for 125 records so I am very happy. I have yet to look at deleting the old file before writing but I am sure that this will make it superb. Many thanks for your help in this. David TotallyObjects http://www.totallyobjects <http://www.totallyobjects/>.com Your suggestion worked perfectly - I truncate the file and it parses > On 11 Feb 2021, at 17:07, <pe...@pbkresearch.co.uk> <pe...@pbkresearch.co.uk> > wrote: > > David > I think you are misreading the debugger display.
