:setvar nter, "!esc""+"&f1m149P<!154>"

Invalid numeric index into the redo stack. (CIWARN 8164)

This warning is because !nnn is treated as referencing command number
nnn from the CI's redo stack.  If command # 154 exists, the entire command
line will be substituted in place of the "!154".

If "!154" needs to be part of the variable's value then use "!!154" instead.

Another concern is that the "<" and ">" can be treated as I/O redirection,
but in this case the quotes prevents that from happening.  If you
want a ">" or a "<" to be treated literally by the CI you can escape the
character with a "!", eg. "!>" or "!<".

My guess is that it has something to do with command line #154.

Clever solution!  If you need to echo this whole string you can do it in one
line:
   :echo ![chr(27)+"&f1m149P<!!154>"]

Here you see an expression inside the ![]
