---+ Vplus on the HP3000

V/Plus is the block-mode terminal interface used on HP3000s. It is an I/O efficient protocol for designing forms on typically 24 line x 80 character per line CRT displays. It includes a form designer tool (FORMSPEC.PUB.SYS) that allows you to create a series of forms, including local edits on fields and hidden fields. It also includes a library of routines that can be called from almost every language on the HP3000 to display and read data from V/Plus forms.
