Test piece for tokeniser
« on: July 26, 2022, 03:56:29 PM »
Quick test of one of the tokenisers. I did not include the win64.inc file in the zip file.

This is the same test piece that now creates a fixed array and copies the tokenised text into the fixed array.

It does one pass through the tokenised lines to get the maximum line length. It allocates the fixed array based off the original array calculation of the maximum line length then copies the original array content to the fixed array.

The purpose of this test piece is to take tokenised data done in place and copy it to an array of fixed member length with additional space so that the lines can be modified up to the new longer length.

As before, the win64.inc file is not included to keep the file size down.
