Bug need help with User Defined Function

Dear Friends,

I need a help regarding User defined function in shell script.

My problem is as follows:

my_func.sh
Code:
my_funcI(){
        grep 'mystring' I.dat
}
my_funcQ(){
       grep 'mystring' Q.dat
}
myfuncI
myfuncQ

But As both the function has same function only the name of the input file is changing I want to pass the file name to the function and merge them to one function. I want something like below ,
Code:
my_func(FILE){
      grep 'mystring' ${FIlE}.dat
}
my_func(I)
my_func(Q)

Please help me wiht a code..

Thanks in advance

my_func()
{
        grep 'mystring' $1
}

my_func  I.dat
my_func  Q.dat

or

Code:
#!/bin/sh

my_func()
{
        grep 'mystring' $1.dat
}

How do do with this code,
Code:
I_plt=/tmp/I_out.plt$$
Q_plt=/tmp/Q_out.plt$$
 
plot(){
  echo "#!/usr/local/bin/gnuplot -persist" > $1_plt
  echo "plot \"$1_indat.txt\" " >> $1_plt
  
 }

  plot I
  cat $I_plt 
  plot Q
  cat $Q_plt

I tried that one it works fine inside double quotes but when I want to replace "$1"in the output redirection it wont works.

user_prady
shall I have to put single qute or double quote for that $1 or > $"$1_plt" .
