Simple Conditional execution in a script

Friends,

We are trying to accomplish a simple conditional exeuction of a 
statement using sed or perl script, 

We are trying to read a line from a file and generate a separate set 
of files based on the lines from that file,

In most cases our source file has a number which tells us how many 
files to create, so we have to read from a file called 07122005.bak, 
which has just a number '25', we need to generate 
07122005_1.bak ..07122005_25.bak

We have tried commands like more, head and cat to read the line into 
a variable so that we could loop that many times, but when we use 
those commands it is inserting a EOF into the variable value which 
negates our downstream use of the variable

our script looks like
cat 07122005.bat > $u
echo $u

This returns
25
EOF

Any suggestions?

BTW, we are on a sun box(solaris)
