3282.0. "Using resource file." by HGOVC::ALFREDLEUNG () Thu Aug 30 1990 04:53

    I hope to know how to use the resoure file to define value of a 
    resource.
    
    Say example, to define the foreground color of the following simple 
    example. I try my best to get these from manual, but I read all the
    manuals that I have, it doesn't tell anything about it. May be I don't
    have the right one that I should have, so please tell me:
    
    1. How to define the name of the resource file?
    2. What is the name of application specific class resource file?
       I only know that it is in DECW$SYSTEM_DEFAULTS directory!
    3. What is the file DECW$XDEFAULTS-HOST.DAT use for?
    4. Which manual should give me this information(I am using VMS)?
    
    I really don't want to ask such these straight forward questions, but
    no manual, no choice, thank for any information.
