NAME
       ckrange,	 errange,  helprange,  valrange - prompts for and validates an
       integer

SYNOPSIS
       ckrange [-Q] [-W width] [-l lower]  [-u upper]  [-b base]  [-d default]
       [-h help] [-e error] [-p prompt] [ -k pid [-s signal]]

       /usr/sadm/bin/errange   [-W width]   [-e error]	[-l lower]  [-u upper]
       [-b base]

       /usr/sadm/bin/helprange	[-W width]  [-h help]  [-l lower]   [-u upper]
       [-b base]

       /usr/sadm/bin/valrange [-l lower] [-u upper] [-b base] input

DESCRIPTION
       The  ckrange  utility prompts a user for an integer between a specified
       range and determines whether this response is valid. It defines,	 among
       other  things,  a prompt message whose response should be an integer in
       the range specified, text for help and error messages,  and  a  default
       value (which is returned if the user responds with a <RETURN>).

       This  command also defines a range for valid input. If either the lower
       or upper limit is left undefined, then the range is bounded on only one
       end.

       All  messages  are limited in length to 79 characters and are formatted
       automatically. Tabs and newlines are removed after a single  whitespace
       character  in  a message definition, but spaces are not removed. When a
       tilde is placed at the beginning or end of a  message  definition,  the
       default	text will be inserted at that point, allowing both custom text
       and the default text to be displayed.

       If the prompt, help or error message is not defined, the	 default  mes‐
       sage (as defined under EXAMPLES) is displayed.

       Three  visual  tool modules are linked to the ckrange command. They are
       errange (which formats and displays an error message  on	 the  standard
       output),	 helprange  (which  formats and displays a help message on the
       standard output), and valrange (which validates a response). These mod‐
       ules  should be used in conjunction with Framed Access Command Environ‐
       ment (FACE) objects. In this instance,  the  FACE  object  defines  the
       prompt.

       Note: Negative "input" arguments confuse getopt in valrange. By insert‐
       ing a "−"  before  the  argument,  getopt  processing  will  stop.  See
       getopt(1)  and intro(1) about getopt parameter handling. getopt is used
       to parse positional parameters and to check for legal options.

OPTIONS
       The following options are supported:

       -b base	       Defines the base for input. Must be 2 to 36, default is
		       10.  Base  conversion uses strtol(3C). Output is always
		       base 10.

       -d default      Defines the default value as default. default  is  con‐
		       verted  using strtol(3C) in the desired base. Any char‐
		       acters invalid in the specified base will terminate the
		       strtol conversion without error.

       -e error	       Defines the error message as  error.

       -h help	       Defines the help message as  help.

       -k pid	       Specifies that process ID pid is to be sent a signal if
		       the user chooses to quit.

       -l lower	       Defines the lower limit of the range as lower.  Default
		       is the machine's largest negative long.

       -p prompt       Defines the prompt message as prompt.

       -Q	       Specifies  that	quit  will  not	 be allowed as a valid
		       response.

       -s signal       Specifies that the process ID pid defined with  the  -k
		       option is to be sent signal signal when quit is chosen.
		       If no signal is specified,  SIGTERM is used.

       -u upper	       Defines the upper limit of the range as upper.  Default
		       is the machine's largest positive long.

       -W width	       Specifies  that prompt, help and error messages will be
		       formatted to a line length of width.

OPERANDS
       The following operand is supported:

       input	       Input to be verified against upper and lower limits and
		       base.

EXAMPLES
       Example 1: Default base 10 prompt

       The default base 10 prompt for ckrange is:

       example% ckrange
       Enter an integer between lower_bound and
       upper_bound [lower_bound−upper_bound,?,q]:

       Example 2: Default base 10 error message

       The default base 10 error message is:

       example% /usr/sadm/bin/errange
       ERROR: Please enter an integer between lower_bound \
	    and upper_bound.

       Example 3: Default base 10 help message

       The default base 10 help message is:

       example% /usr/sadm/bin/helprange
       Please enter an integer between lower_bound and upper_bound.

       Example 4: Changing messages for a base other than 10

       The  messages  are changed from ``integer'' to ``base base integer'' if
       the base is set to a number other than 10. For example,

       example% /usr/sadm/bin/helprange -b 36

       Example 5: Using the quit option

       When the quit option is chosen (and allowed), q is returned along  with
       the return code 3. Quit input gets a trailing newline.

       Example 6: Using the valrange module

       The  valrange module will produce a usage message on stderr. It returns
       0 for success and non-zero for failure.

       example% /usr/sadm/bin/valrange
       usage: valrange [-l lower] [-u upper] [-b base] input

EXIT STATUS
       The following exit values are returned:

       0	Successful execution.

       1	EOF on input, or negative width on -W option, or usage error.

       2	Usage error.

       3	User termination (quit).
