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

  The SEQUENCE command tells BASIC to automatically generate line  numbers
  for the input of program text.  The default for the starting line number
  (line-num) is 100 and the default increment  (int-const)  is  10.   Type
  CTRL/Z to terminate the sequencing operation.

  Example

  SEQUENCE 10,5

  Format

      SEQUENCE [ line-num ] [, int-const ]
