Brian,
R and MatLab are both widely used for array processing (and time-series), and each has a read function which allows the specification of a delimiter character.
Read.delim in R:

textread command in Matlab:

Just two examples of how other array-based programs do it. While both of the programs mentioned above are tops in terms of pure numerical analysis, when you want to add buy/short/sell/cover conditions and put in any slightly complicated strategy then we turn to Amibroker.
