TechWhirl (TECHWR-L) is a resource for technical writing and technical communications professionals of all experience levels and in all industries to share their experiences and acquire information.
For two decades, technical communicators have turned to TechWhirl to ask and answer questions about the always-changing world of technical communications, such as tools, skills, career paths, methodologies, and emerging industries. The TechWhirl Archives and magazine, created for, by and about technical writers, offer a wealth of knowledge to everyone with an interest in any aspect of technical communications.
Thanks to all who responded to my function, routine, subroutine
question. I decided to go with function because they all
returned a value. I also decided to forgo the parens because
I can use function as a modifier in the text and use the parens
in the syntax statements and examples. I asked some programmers
what the difference between the terms is and, as David Hamilton
predicted, they said they're all the same thing. I guess it
takes a bunch of tech writers to quibble about definitions.
