Library /sys$common/syshlp/basichelp.hlb ON, GOTO  *Conan The Librarian (sorry for the slow response - running on an old VAX)

  The ON GOTO statement transfers program  control  to  one  of  several
  lines, depending on the value of a control expression.

  Example

  330    ON Index% GOTO 700, 800, 900 OTHERWISE 1000
