argument is placed in a parameter. For example, in the CRBasic command
Battery(dest), dest is a parameter that defines what argument is to be put in
its place in a CRBasic program. If a variable named BattV is to hold the
result of the battery measurement made by Battery(), BattV is the argument
placed in dest. In the statement
Battery(BattV)
BattV is the argument.
