Help with Keyed List Arguments

I am trying to send this in as a key value pair in tcl proc –>

{MAP \E\ ” ” \F\ ” ” \S\ ” ” \R\ ” ” \T\ “and”}

I received this error–>

hcitpstest: QDX_Tcl_SplitList(tps_escape_char

{MAP {\E\ ) failed — unmatched open brace in list

I have tried many combination, but still receive the unmatched open brace in list error.

I want to pass this list to a string map in proc so I can reuse the proc.  One thing I tried was to just pass something like this–>

{MAP {E “”}} and still received the same error…so it must be “” but a need those characters  😈

Anyone have any ideas?? 😮
