append esc string

I have a request that is simple, but I can't figure out how to do it. I have a unix file that I want to append the following string to the front of the file


<esc>&l1O<esc>(0U<esc>(s0p16.66h8.5v0s0b0T


and an


<esc>E


to the end. I know that I could do something like

cat start_file report_file end_file > new_report_file

However, I can't figure out how to save the ESCAPE character in the start and end file. I feel silly asking this, but I have never had to do it before.

NAME
append - Append to variable SYNOPSIS
append varName ?value value value ...? _________________________________________________________________ DESCRIPTION
Append all of the value arguments to the current value of variable varName. If varName doesn't exist, it is given a value equal to the concatenation of all the value arguments. The result of this command is the new value stored in variable varName. This command provides an efficient way to build up long variables incrementally. For example, ``append a $b'' is much more efficient than ``set a $a$b'' if $a is long. EXAMPLE
Building a string of comma-separated numbers piecemeal using a loop. set var 0 for {set i 1} {$i<=10} {incr i} { append var "," $i } puts $var # Prints 0,1,2,3,4,5,6,7,8,9,10 SEE ALSO
