Assuming you're using a shell that recognizes arrays, the following seems to avoid your syntax and logic errors:
Code:
#Initialize arrays
for ((i=1 ; i <= $2; i++))
do	echo "Enter starting digit of $i string"; read a[i]
	echo "Enter length in digits of $i string"; read b[i]
done 

#Skim through file, slice strings
while read line
do	for ((i=1; i < $2; i++))
	do	printf '%s ' "${line:${a[i]}:${b[i]}}"
	done
	printf '%s\n' "${line:${a[$2]}:${b[$2]}}"
done <$1

Note that the output you showed would come from the input 1,3 and 3,4; not 1,2 and 3,4.

glgenvertexarrays

GLGENVERTEXARRAYS(3G)						  [FIXME: manual]					     GLGENVERTEXARRAYS(3G)

NAME

       glGenVertexArrays - generate vertex array object names

C SPECIFICATION

       void glGenVertexArrays(GLsizei n, GLuint *arrays);

PARAMETERS

       n
	   Specifies the number of vertex array object names to generate.

       arrays
	   Specifies an array in which the generated vertex array object names are stored.

DESCRIPTION

       glGenVertexArrays returns n vertex array object names in arrays. There is no guarantee that the names form a contiguous set of integers;
       however, it is guaranteed that none of the returned names was in use immediately before the call to glGenVertexArrays.

       Vertex array object names returned by a call to glGenVertexArrays are not returned by subsequent calls, unless they are first deleted with
       glDeleteVertexArrays().

       The names returned in arrays are marked as used, for the purposes of glGenVertexArrays only, but they acquire state and type only when they
       are first bound.

ERRORS

       GL_INVALID_VALUE is generated if n is negative.

SEE ALSO

       glBindVertexArray(), glDeleteVertexArrays()
