SDSU_AskLib is a collection of VAX Fortran-77 routines that can be used in
interactive programs to prompt a user for input, accept user input, and check
the validity of user responses. The routines handle additional details such as
converting input, displaying error messages, reprompting and looping,
processing nested input files and, if enabled, logging input to a journal file.
SDSU_AskLib was created at the San Diego State University (SDSU)
University Computer Center (UCC) in 1984. It was available through the DECUS
library and has now been located on launchpad.net.
