Replace Text

Hello,

I am readng some text data from a file. The format of the text is:

ASPUL -16.00E-03 -17.00E-03 -18.00E-03 -19.00E-03 -20.00E-03 +
-21.00E-03 -22.00E-03 -23.00E-03 -24.00E-03 -25.00E-03 +
-26.00E-03 -27.00E-03 -28.00E-03 -29.00E-03 -30.00E-03 +

I would like to replace ASPUL with ASPULN. I am reading the data using the line code

Line Input #iAxialProfFileMinNum, LineData


My problem is that the numbers followed by ASPUL can change bazed on certain other factors.
I need a logic that will let me split the string into 2 strings with a space separator, changing the first string to ASPULN and then appending the second string consisting of the numbers.
Any ideas as to how to do this? or any other better way

Thanks
