These programs were developed at CIMMYT for conducting field socioeconomic surveys by means of expand PDAs and expand PCs. The process of collecting data in the PDA or PC consists of designing the survey on the PC, taking the questions from the questionnaire, and programming them. This generates the template containing the questions in a file with extension .ssf. This file allows the socioeconomic survey form (SSF) for the PDA, as well as the SSF for the PC, to interpret the template and design the backbone of the questionnaire on the screen, capturing the survey data by means of a set of validation rules in the program. The survey tools are divided into two programs.
