How to read/write CSV file with Lauterbach CMM script row by row

I'm trying to read/write a CSV file row by row using Lauterbach CMM script, but it's not working.

I thought I can read each row of CSV file as each line if I read csv as normal file, but it's not true, if you use LF characters in the cell data: Reading CSV file line by line will be terminate. I mean the script reads the row as partially.

Can you please let me know to read CSV file row by row?

My code to read CSV row by row :

OPEN #1 &csv_name /Read
WHILE !FILE.EOF(1)
(
    READ #1 %LINE &csv_row
    PRINT "&csv_row"
)

Can you please provide information on how to read/write CSV file row by row by using a Lauterbach CMM script?

The way you are using OPEN and READ is intended to read one line of a text file. They are not made especially for CSV files. And while CSV files may have a line-feed-character inside a line (when encapsulated in double-quotes), a line of a normal text file simply ends with a line-feed.

So I think you have two options here: Read the file byte by byte as a binary file or load the whole file to the debuggers virtual memory (VM) and read it from there byte by byte.

Option 1 : Read the file byte by byte

OPEN #1 "&csv_name" /Read /Binary
WHILE !FILE.EOF(1)
(
    PRIVATE &line
    GOSUB getline "1"
    RETURNVALUES &line
    IF "&line"!=""
        ECHO "&line"
)
CLOSE #1
ENDDO

getline:
    PARAMETERS &fh
    PRIVATE &c &last &line &inquotes

    &last=0
    &inquotes=FALSE()

    READ #&fh &c
    WHILE !FILE.EOF(&fh)
    (
        IF (&last=='"')&&(&c!='"')
            &inquotes=!&inquotes
        IF (!&inquotes)&&(&c==CONvert.CHAR(0x0A))
        (
            IF &last==CONvert.CHAR(0x0D)
                &line=STRing.CUT("&line",-1)
            RETURN "&line"
        )
        &line="&line"+CONvert.CHAR(&c)
        &last=&c
        READ #&fh &c
    )
    RETURN "&line"

Option 2 : Load the whole file to the debuggers virtual memory (VM) and read it from there byte by byte.

PRIVATEn &line &size &pos

&pos=0    
&size=OS.FILE.SIZE("&csv_name")
SILENT.Data.LOAD.Binary "&csv_name" VM:&pos
WHILE &pos<&size
(
    GOSUB getline "1" "&pos" "&size"
    RETURNVALUES &line &pos
    IF "&line"!=""
        ECHO "&line"
)
CLOSE #1
ENDDO

getline:
    PARAMETERS &fh &pos &size
    PRIVATE &c &last &line &inquotes

    &last=0
    &inquotes=FALSE()

    WHILE &pos<&size
    (
        &c=Data.Byte(VM:&pos)
        &pos=&pos+1
        IF (&last=='"')&&(&c!='"')
            &inquotes=!&inquotes
        IF (!&inquotes)&&(&c==CONvert.CHAR(0x0A))
        (
            IF &last==CONvert.CHAR(0x0D)
                &line=STRing.CUT("&line",-1)
            RETURN "&line" "&pos"
        )
        &line="&line"+CONvert.CHAR(&c)
        &last=&c
    )
    RETURN "&line" "&pos"
