Library /sys$common/syshlp/lse$clihelp.hlb LINE, Parameters  *Conan The Librarian (sorry for the slow response - running on an old VAX)

 integer
    Specifies the number of the line in the current buffer to which
    you want LSE to move the cursor. If you do not specify a line
    number, LSE prompts for one. Pressing CTRL/Z at the prompt cancels
    the command.

 procedure-name
    Specifies the name of a VAXTPU procedure in the current buffer.
    The procedure name is valid only for VAXTPU source files. This
    parameter is useful because some compiler messages refer to line
    numbers in a procedure.

    To find out the current line number and total number of lines in
    the buffer, use the WHAT LINE command.
