SQL*Loader sqlldr removes zeros from character field

Question

Hello,
I am using SQL*Loader to load an Oracle table, and am having a problem. One of the fields is defined as VARCHAR2 and contains comments entered by a user. There may be numbers or dollar amounts included in this text. When I execute the sqlldr script below, the result is that all of the zeros on the text field disappear. There is a translate function invoked for this field (bolded statement) in an attempt to remove imbedded newlines from the text. Wherever there was a zero in the original text, it ends up being removed after I run this script. Can anyone suggest why this is occurring, and how to prevent it? Can it be related to the translate function?
Thanks for your help!

Never mind, found my mistake. In the TRANSLATE function, I had assumed that the 0x0A would be interpreted as a single hex value. Instead, it is interpreted literally as the character '0', the character 'x', the character 'A', etc. The result is that the transformed text had no '0', 'x', or 'A' characters, which is exactly what I inadvertently told it to do. I changed it to the following, which works better ;-)
RST_EXTENDED_TXT "SUBSTR(TRANSLATE(:RST_EXTENDED_TXT, '#'||CHR(10), '#'), 1, 250)"
