Examples of dialog box programming in Stata: data entry and telephone randomisation

The dialog box and menu commands introduced in Stata 5.0 can be used to turn
Stata into a customised data-handling environment. This allows, for instance,
data-entry directly into a Stata dataset, dispensing with the need for a
separate database and transfer protocol. This approach to data collection is
attractive for small to medium size studies where the statistician is actively
involved in the conduct of the study. The more laborious aspects of
programming dialog boxes in Stata have been taken on by the
winshow command (STB-46), allowing the
statistician to concentrate on the database design and coding scheme.
The winshow command can interface to user-written data
checking programs, providing some flexibility in its application. This aspect
will be illustrated by a randomisation utility that is being used in a major
UK clinical trial.
