PowerBuilder Code Beautifier / Formatter

We then loop through each token and determine if it's a keyword, datatype, quote, comment, carriage return, or user defined text (like variable names).

Below is what we'll create. We'll use the PB Chromium Web Browser control with the Ultimate Suite for PowerBuilder Tabbed Caption window.



Some things we'll accept right away; 1) This browser is extremely basic so we won't hav…
