Switches

Switches are arguments used with LOAD-class (COMPILE,  LOAD,  EXECUTE,
and  DEBUG) and EDIT-class (CREATE and EDIT) commands, as well as with
Queue-class commands - that is, those affecting entries in  processing
queues  (CANCEL,  DISMOUNT,  MODIFY,  MOUNT,  PLOT,  PRINT, PUNCH, and
SUBMIT).

Switches can also be used with the following program-control commands:
DDT,  GET,  MERGE,  R,  and  RUN.   The  REWIND command also accepts a
switch.

Switches allow you to quickly give many options chosen  from  a  large
list, and let you specify to which files they apply when you give more
than one filespec in a single command.

Give switches on the same line as the  command,  typing  a  slash  (/)
before  each  switch.   If  your  command requires more than one line,
simply keep typing without giving a carriage return.  The system  will
begin  a  new  line automatically and will read your command as if you
had typed it on a single line.  Or you can end your  command  line  at
any  point  with  a  hyphen  (-) and carriage return, and continue the
command on the next line; the hyphen will not be  considered  part  of
your input.

Keep in mind  the  way  each  class  of  command  considers  switches.
EDIT-class  commands  operate  on  only  one  file  at a time, and the
switches must  be  given  before  the  input  filespec - this  is  the
simplest case.

Queue-class and LOAD-class commands treat switches according to  their
position  in the command line.  If you give them before any filespecs,
they act as default switches for all filespecs in  the  command  (they
will  be  in  effect  unless  you  override  them  with later switches
applying to individual files only).  If you give them after the  first
filespec,  they  apply only to the preceding file.  In addition, there
are a few switches of a different sort for the PLOT, PRINT, and  PUNCH
commands - these apply to all files no matter where they appear in the
command line.  These are called job switches (because they affect  the
entire  printing  job)  and  are presented in a separate list in those
command descriptions.

A switch is a default if the system  assumes  it  in  the  absence  of
others.  For example, for LOAD-class commands, /FORTRAN is the default
for all switches that specify which  compiler  to  use  (like  /MACRO,
/COBOL,  and  /PASCAL).   The  /NOCOMPILE  switch  is  the default for
/COMPILE, /NOCOMPILE,  and  /RELOCATABLE.   Most  defaults  for  these
commands  apply  to  only  a  pair  of switches; however, the /BINARY,
/NOSEARCH, and /NOOPTIMIZE switches are assumed, for  example,  unless
you specify /NOBINARY, /SEARCH, and /OPTIMIZE.

Default switches for the other classes of command  operate  similarly.
Some  are  in  effect unless you specify their opposite; others are in
effect with a default argument unless you  specify  another  argument;
still  others must be specified to be in effect, but are supplied with
a default argument.  The list of switches presented with each  command
description  distinguishes  these  cases.   When  you give two or more
switches of the same kind (for example, /BINARY  and  /NOBINARY),  the
last switch given usually prevails.
