You can do

   put baseConvert("1B", 16, 10) into t
   put numtochar(t) after theOutputString

for each character.

Note that what you have above is actually the same line repeated , i.e.

<ESC> “d” “0” or <ESC> “d” <0>
is the same as 
(1B)H (64)H (30)H or (1B)H (64)H (00)H

and 

<ESC> “d” “1” or <ESC> “d” <1>
is the same as
(1B)H (64)H (31)H or (1B)H (64)H (01)H



So (what I'd do :-) ...
   put numtochar(27) into cESC    -- ESC is ascii 27 is 1B(H)
then
   put cESC & "d0" after theOutputString  
or
   put cESC & "d1" after theOutputString
