Modified version of the script to process the input parameters in order:
Notice the use of "shift" to cause each parameter in turn to be called $1 .

Code:
#!/bin/sh

a=$#    #number or parameters
b=0      #starting counter

while [ $a -gt $b ]
do
   b=`expr $b + 1`
   echo "Parameter $b is $1"
   shift
done

./scriptname a b c
Parameter 1 is a
Parameter 2 is b
Parameter 3 is c

NAME
glGetHistogramParameterfv, glGetHistogramParameteriv - get histogram parameters C SPECIFICATION
void glGetHistogramParameterfv( GLenum target, GLenum pname, GLfloat *params ) void glGetHistogramParameteriv( GLenum target, GLenum pname, GLint *params ) PARAMETERS
target Must be one of GL_HISTOGRAM or GL_PROXY_HISTOGRAM. pname The name of the parameter to be retrieved. Must be one of GL_HISTOGRAM_WIDTH, GL_HISTOGRAM_FORMAT, GL_HISTOGRAM_RED_SIZE, GL_HISTOGRAM_GREEN_SIZE, GL_HISTOGRAM_BLUE_SIZE, GL_HISTOGRAM_ALPHA_SIZE, GL_HISTOGRAM_LUMINANCE_SIZE, or GL_HISTOGRAM_SINK. params Pointer to storage for the returned values. DESCRIPTION
glGetHistogramParameter is used to query parameter values for the current histogram or for a proxy. The histogram state information may be queried by calling glGetHistogramParameter with a target of GL_HISTOGRAM (to obtain information for the current histogram table) or GL_PROXY_HISTOGRAM (to obtain information from the most recent proxy request) and one of the following values for the pname argument: Parameter Description GL_HISTOGRAM_WIDTH Histogram table width GL_HISTOGRAM_FORMAT Internal GL_HISTOGRAM_RED_SIZE Red component counter size, in bits GL_HISTOGRAM_GREEN_SIZE Green component counter size, in bits Parameter Description GL_HISTOGRAM_BLUE_SIZE Blue component counter size, in bits GL_HISTOGRAM_ALPHA_SIZE Alpha component counter size, in bits GL_HISTOGRAM_LUMINANCE_SIZE Luminance component counter size, in bits GL_HISTOGRAM_SINK Value of the sink parameter NOTES
glGetHistogramParameter is present only if GL_ARB_imaging is returned when glGetString is called with an argument of GL_EXTENSIONS. ERRORS
GL_INVALID_ENUM is generated if target is not one of the allowable values. GL_INVALID_ENUM is generated if pname is not one of the allowable values. GL_INVALID_OPERATION is generated if glGetHistogramParameter is executed between the execution of glBegin and the corresponding execution of glEnd. SEE ALSO
