Free rejection hotline software for pda

PalmKey by Cam presents the user with a series of characters for which character state information is entered about the entity in question.
The list of possible taxa is reduced at each step.
PalmKey databases are maintained as JFile files, and are easy to create and modify. Coded in PocketC.
Main features:
- Data is stored as a JFile database. This enables data entry and editing, on the Palm. Note, however, that JFile is not needed to run a key. A demo version of JFile is available for free.
- Up to 50 characters (a limitation of JFile databases).
- Up to 9 states per character.
- No theoretical limit on number of taxa, but performance decreases with increasing taxa number. A practical maximum is ca. 200 taxa.
- Multiple states allowed for each character for each taxon.
- Unknown character states (coded as a `?\) for a taxon do not cause the rejection of the taxon.
System requirements:
- Palm III
- Palm OS v3.0
- PocketC Runtime
