Using Variables to Specify Buffer Numbers

Buffer numbers on a command line must be integers. VISTA provides a way of using variables to denote buffer numbers. Place the name of the variable on the command line in place of the buffer specification, with a $ character in front of the variable name.

Examples:
\begin{example} \item[MN \$J\hfill]{mean of buffer J} \item[ADD \$BUF CONST=5\hfill]{add 5 to buffer BUF} \end{example}
