Subject: Escaped backslashes in input strings - newbie question

In Icon a solution looks like this:

########################################################
#
#    Procedure to remove escaped characters from
#    CINDEX DAT file
#
########################################################
#
#    Scan string to find each "\" character.
#    Remove it and the following character.
#
########################################################


procedure remesc(s)
     local outputstring
     outputstring := "" # initialise
     s ? {
         while outputstring ||:= tab(upto('\\')) do move(2)
         outputstring ||:= tab(0)
     }
     return outputstring
end
