KEYWORD
Keywords are instructions recognized by a decoder within the BOP, referred to as a “parser.”
Each keyword describes a command function; all keywords used by the BOP are listed in Figure
3-27.
Each keyword has a long form and a short form. For the long form the word is spelled out com-
pletely (e.g. STATUS, OUTPUT, VOLTAGE, and TRIGGER are long form keywords). For the
short form only the first three or four letters of the long form are used (e.g., STAT, VOLT, OUTP,
and TRIG). The rules governing short form keywords are presented in Table 3-22. There are
exceptions to the rules, where only the long form is accepted. These exceptions are docu-
mented in the Appendices as applicable.
