To handle both "h" (horizontal dots) and "v" (vertical dots) in the same script you will need to change the structure of the script slightly bearing in mind the previous post about the different ways of comparing strings and integers.

A script becomes easier to read if we save the input parameters to named variables early in the script.

For example:

Code:
if [ $# -ne 2 ]
then
    echo "Usage: `basename $0` [h|v] dot_count"
    exit
fi
#
dot=0
orientation="$1"
dot_count=$2

while [ ${dot} -lt ${dot_count} ]
do
   # Horizontal
   if [ "${orientation}" = "h" ]
   then
       printf "."       # No linefeed
   fi
   # Vertical
   if [ "${orientation}" = "v" ]
   then
       printf ".\n"     # With linefeed
   fi
   #
   dot=`expr $dot + 1`
done
#
if [ "${orientation}" = "h" ]
then
   printf "\n"  # End the horizontal dots with a linefeed
fi

SYNOPSIS

       #include <Xm/Xm.h>

       int XmConvertUnits (widget, orientation, from_unit_type, from_value, to_unit_type)
	       Widget widget;
	       int orientation;
	       int from_unit_type;
	       int from_value;
	       int to_unit_type;

DESCRIPTION

       XmConvertUnits  converts  the value and returns it as the return value from the function.  Specifies the widget for which the data is to be
       converted Specifies whether the converter uses the horizontal or vertical screen resolution when performing the	conversions.   orientation
       can  have  values of XmHORIZONTAL or XmVERTICAL.  Specifies the current unit type of the supplied value Specifies the value to be converted
       Converts the value to the unit type specified

       The parameters from_unit_type and to_unit_type can have the following values: XmPIXELS--all values provided to the widget  are  treated	as
       normal  pixel  values.	This is the default for the resource.  Xm100TH_MILLIMETERS--all values provided to the widget are treated as 1/100
       millimeter.  Xm1000TH_INCHES--all values provided to the widget are treated as 1/1000 inch.  Xm100TH_POINTS--all  values  provided  to  the
       widget  are  treated  as  1/100	point.	A  point  is  a  unit  typically used in text processing applications and is defined as 1/72 inch.
