Highlight source files from your keyboard

Highlighting source code with 5250 display attributes can improve readability and help to focus one's attention on what is going on in the program.�Most programmers are unaware that code may be highlighted without using a purchased or homegrown utlity.�While these are useful (I wrote one of the latter for myself), the highlighting effect can be extended by embedding display attributes directly from your keyboard.�Using the CA/400 Customize Keyboard function, which may be accessed via menu option Assist | Keyboard Setup... | Customize, or the toolbar button (if enabled), you can assign values of "apl xx" (don't include the quotes) to any valid key combination, where "xx" is a hexadecimal value.� The complete set of valid 5250 display attribute codes are shown below.

When highlighting a source member, remember to place the attibutes into an area of the source line that will not cause a syntax or compile-time error, such as columns ont to five of any RPG specification.
