This had me puzzled for a while, but I think I figured out what is wrong. I found this
Quote:
Because the transliteration table is built at compile time, neither the SEARCHLIST nor
the REPLACEMENTLIST are subjected to double quote interpolation. That means that
if you want to use variables, you must use an eval():
So the tr command is trying to translate the letters "$", "v", "a", and "l", not the value that $val contains.
I have two files I want to compare, one is a list of variables and the other is a text file COBOL program.
Basically what I want to do is display only those variables that appear in the COBOL program only once. However I would also accept a count of each variable as it appears in the COBOL... (2 Replies)

Stream(3o) OCaml library Stream(3o)NAME
Stream - Streams and parsers.
Module
Module Stream
Documentation
Module Stream
: sig end
Streams and parsers.
type 'a t
The type of streams holding values of type 'a .
exception Failure
Raised by parsers when none of the first components of the stream patterns is accepted.
exception Error of string
Raised by parsers when the first component of a stream pattern is accepted, but one of the following components is rejected.
=== Stream builders Warning: these functions create streams with fast access; it is illegal to mix them with streams built with [< >];
would raise Failure when accessing such mixed streams. ===
val from : (int -> 'a option) -> 'a t
Stream.from f returns a stream built from the function f . To create a new stream element, the function f is called with the current
stream count. The user function f must return either Some <value> for a value or None to specify the end of the stream.
val of_list : 'a list -> 'a t
Return the stream holding the elements of the list in the same order.
val of_string : string -> char t
Return the stream of the characters of the string parameter.
val of_channel : Pervasives.in_channel -> char t
Return the stream of the characters read from the input channel.
=== Stream iterator ===
val iter : ('a -> unit) -> 'a t -> unit
Stream.iter f s scans the whole stream s, applying function f in turn to each stream element encountered.
=== Predefined parsers ===
val next : 'a t -> 'a
Return the first element of the stream and remove it from the stream. Raise Stream.Failure if the stream is empty.
val empty : 'a t -> unit
Return () if the stream is empty, else raise Stream.Failure .
=== Useful functions ===
val peek : 'a t -> 'a option
Return Some of "the first element" of the stream, or None if the stream is empty.
val junk : 'a t -> unit
Remove the first element of the stream, possibly unfreezing it before.
val count : 'a t -> int
Return the current count of the stream elements, i.e. the number of the stream elements discarded.
val npeek : int -> 'a t -> 'a list
npeek n returns the list of the n first elements of the stream, or all its remaining elements if less than n elements are available.
