This does not solve the problem. gets() only gets one line (up to \n) from
the file, but does not separate the items as delimited by commas. After
that, you should use the value() function.
But value() has a shortcoming: after getting the first numerical item up to
the following space or comma (or any non-numerical character), it does not
show the point up to which it got. What Euphoria needs is a function,
similar to value(), which also returns the index of the following character
in the string.

Strtok.e has:
gettok() to get the data tween the commas
toknum() to count the data tween the commas
gettok() to get the data item you specify
instok() to put a data item in tween commas
deltok(),, well, you get it
reptok() replace a certain data field
parse() to return the data items in gets() as sequences
deparse() to make a nested seq into a sentence or comma delinited string or
whatever.
etc
and you can spec as delimiters a comma, semicolon, or any other one-byte
char. If you pass gettok() a paragraph with sentences delimited with ascii 10,
use gettok(paragraph,10). To get words out of the sentence, use a ' ' or 32. (
at least i think i updated that before sending it in to RDS, make all the "char
c" in the functions into "integer c".) Also, empty data fields in a comma
delimited line may not be parsed properly, so comment out these lines in
parse():
-- doublec = c & c
-- while match(doublec,s) do
-- s = s[1..match(doublec,s)] & s[match(doublec,s)+2..length(s)]
-- end while
