I'm having a hard time introducing an integer which I have defined in script to a simple "sed" command 
I have declared variable in script like this
PHP Formatted Code int F =0
Now I put this in a while loop and get a particular value assigned to it. To know which file name this value corresponds to, I use this command
PHP Formatted Code !sed 'Fq;d' flats
where F is the integer and flats is a list of flat images.
Please help me out on this

What you're trying to do is mix literal strings and script variables, which you can do, but you have to create a new command string and then use the CL to execute it. For example,
PHP Formatted Code print ("!sed '" // F // "q;d' flats") | cl()
where the '//' is the string concatenation operator and the value of the F variable is put into the string.
If all you're doing is looping over the contents of the 'flats' file, the CL way to do this is
PHP Formatted Code
list = "flats"
while (fscan (list, s1 ) != EOF ) {
... do something withe 's1' variable that contains the next line of the file
}
