Ideally, avoid scripts, and do all the processing on the IOC.
Especially when you don’t know how to use scripts, it’s better to avoid them.

If you have several records and you want to select one of them, check the select (“sel”) record, http://www.aps.anl.gov/epics/EpicsDocumentation/AppDevManuals/RecordRef/Recordref-33.html

Somewhat like this:

# PV Shown in a combo box that allows selecting one of the 6 sources
record(mbbi, “choose_one”)
{
  field(ZRVL, “0”)
  field(ZRST, “Option A”)
  field(ONVL, “1”)
  field(ONST, “Option B”)
 …
}

# Record that will hold the value of one of the six data PVs.
# Simply display this record in the user interface
record(sel, “active_value”)
{
  field(SELM, “Specified”)
  field(NVL, “ choose_one”)
  field(INPA, “record_for_option_A”)
  field(INPB, “record_for_option_A”)
 …
}

Add FLNK or CP or .. do trigger processing as desired.
