Hello,
I need to read first line in a file, and I am using the
following three lines.

FOR /F "eol=; tokens=1" %%i in (%myFile%) do (set myPar=%%
i &GOTO:forend)
:forend
Echo %myPar%
There are other lines after this, that performs some other
operations.

Is this correct and secure way? I do not want FOR goes to
second line and print %myPar% again, that will cause
trouble.
Thanks,
Jim.

What must terminate the line for the set command? EOL? CR? Both? Either?

Nothing. When the end of the pipe is detected, everything (within
reason) read upto that point is a assigned to the variable, unless
a carriage return (0x0D) is encountered, then just everthing before
the CR is assigned.
