[fpc-pascal] how to use Default to replace this " FillChar(aRecord, sizeof(aRecord), 0);

In this old statement, I don't need to know the type of aRecord but if I want to use Default, I have to know the exact type of the varaible aRecord and pass it to Default(aRecordType) e.g. aRecord := Default(aRecordType) //where var aRecord : aRecordType Is it possible to use default

[fpc-pascal] performance when resizing a dynamic array

Hi, If I use an array to hold a list of say Integers. Is there any serious performance penalty for resizing (growing) the dynamic array as I add items. My point being, I don't know the number of elements I'll need beforehand. Regards, Graeme -- fpGUI Toolkit - a cross-platform GUI toolkit

[fpc-pascal] List of integers? Any class available in RTL or FCL to help?

Hi, The code I'm working on often needs a list of integers (actually uint16, int16 etc, but Integer should do). I would normally use an array, but I have no idea how many items I'll need beforehand. Obviously I could take 15 minutes and implement my own TIntList class or something, but that got
