When you post topics to this board, you will notice that there are two buttons for specifying APL text.
The button 'APLCodeSample' should be used for posting code samples in the APL font, with blank spacing retained. Use this for posting multiple lines of APL code.
The button 'APLFont' sets the font only; use this for embedding APL symbols within a sentence without starting a new line.
In both cases, you need to enter the APL symbols using Unicode (UTF-8) encoding. The easiest way of doing this is to enter the text within APLX, select it, and choose 'Copy As Unicode' from the Edit menu. The paste the text into the 'Post a topic' edit window in your browser.
You can also copy APL text from other Unicode-aware applications such as NotePad, IBM APL2, Dyalog APL, etc.
