Hi everybody, I am new on IDL and I will be very grateful if someone
could help me

I have an array of value (X,Y) and I want all Y data negative equals
to 1:
x y
1 84
2 90
3 14
4 -75
5 -95
6 -27

so I guess the correct way to apply this filtering is working with IF
and THEN:

IF x LT 0 then x = 1

but I got an error:
"Expression must be a scalar or 1 element array in this context: <BYTE
Array[2, 6]"
How I can resolve this problem?

Thanks in advance
Cico
