Subject: Re:  resize initializes whole array

There is no argument against the ISO standard, but to a non C/C++ programmer 
it seems a waist of time to reallocate the array and initialize it when one 
wants to add something to an array. Some other compilers will copy the 
existing data into the newly allocated space which seems more in line with 
the text book.
The application will be changed to avoid the loss of data on a resize of 
arrays, which is a better idea anyway. Thanks for the speedy reply.
