[Scilab-users] How replace symbols and letters in a matrix

[constantina]

Hello everyone (first of all, sorry 4 my poor english), im newbie in scilab.
Im trying to process data, it includes a header and a matrix with numbers,
letters and symbols.  I used Data=fscanfMat(flist(file)) to read the matrix
without the header; but i can read only the first line (and till the 8
column) then I obtain zeros... i have problems with the symbol * and the
letter S. I cant use linux for replace the caracters...  The form of the
data is: 

/Gem Systems GSM-19W 2065231 v7.0 12 IX 2011 M ew3fl.v7o 
/ID 1 file 02survey.wm 04 VII12
/
/X Y elevation nT sq cor-nT sat time picket-x picket-y 
line 000000
0369875.71 7435000.99 000780 23623.80 99 000000.00 08 S 141058.0 0 0 
0369875.71 7435000.99 000780 23623.91 99 000000.00 08 S 141058.5 * * 
0369875.71 7435000.99 000780 23623.60 99 000000.00 08 S 141059.0 * * 
0369875.71 7435000.99 000780 23623.01 99 000000.00 08 S 141059.5 * * 
0369875.71 7435000.99 000780 23623.99 99 000000.00 08 S 141100.0 * *

I have to replace the S and * for a zero
How can I do it???
