KSH/bash for File Creation Dynamically

I have a directory name tmp on that directory on basis of FileName Category I wanted to create 'n' number of files dynamically.
if [ ! -d tmp ]
then
mkdir tmp
fi
TEMPDIR=$HOME/tmp
cd $TEMPDIR
array_FileName_category[0]="File1"
array_FileName_category[1]="File2"
array_FileName_category[2]="File3"
array_FileName_category[3]="File4"
a=0
while [ $a -le 9 ]
do
### Creating Source Files
${array_FileName_category[$a]}_file=$TEMPDIR/${array_FileName_category[$a]}_file_$$
a=`expr $a + 1`
done
but this is not working and giving the following errors:
File Not found with array prefix.
and the other error is for zero index of array ${array_FileName_Category[$a]} is not working
My Desired Output is: If there is FileCategory 'Sports' then at tmp directory using the while loop it will create a file with prefix Sports

Because arrays management in korn shell is far away from other programming languages you can try something like:
Instead of this:
while [ $a -le 9 ]
do
${array_FileName_category[$a]}_file=$TEMPDIR/${array_FileName_category[$a]}_file_$$
a=`expr $a + 1`
done
try this:
while [ $a -le 9 ]
do
b=$array_FileName_category[$a]
touch $TEMPDIR/${b}_file_$$
a=`expr $b + 1`
done
P.S. And IMHO for loop will be better for this purpose

It is giving error File1_file=../tmp/File1_file_33555804: not found. which means it is not taking as creation of file rather it is taking assignment as a file.

If you want to create a file see my changes in the script
– Romeo Ninov
Apr 6 '15 at 10:24
this time there is not any error message but on ls -ltr the files are not getting listed , means files count is displaying 8 but there is not any file.
