Hi,

Make use of 'Scan' statement to get the number of lines with out comments.

SCAN ABAP-SOURCE itab1 ...TOKENS INTO itab2

...STATEMENTS INTO itab3.

ABAP-SOURCE is the program name

You can use the statement 'With comments' and without it and do a computation to get the number of commented lines.

Hi,

Check below Code,

REPORT ZCOMMENT.

************************************************************************

This program subtracts the comment lines from a program source.
To get the line numbers right, run pp before the subtraction.
It can be useful to document abap developments

************************************************************************

PARAMETERS: PROGRAM LIKE SY-REPID DEFAULT SY-REPID.

DATA : BEGIN OF SOURCE OCCURS 1000,

LINE(72),

END OF SOURCE.

DATA: I TYPE I, J TYPE I, K TYPE I, L TYPE I, LNUM(6) TYPE N.

DATA: EMPTY(72) VALUE

'. "Some ugly long line

DATA: P_STATEMENTS LIKE SSTMNT OCCURS 100 WITH HEADER LINE.

DATA: P_TOKENS LIKE STOKEN OCCURS 100 WITH HEADER LINE.

READ REPORT PROGRAM INTO SOURCE.

SCAN ABAP-SOURCE SOURCE STATEMENTS INTO P_STATEMENTS "Comment in chain

TOKENS INTO P_TOKENS.

Remove the statement closing characters

LOOP AT P_STATEMENTS.

IF P_STATEMENTS-TROW <> 0.

READ TABLE SOURCE INDEX P_STATEMENTS-TROW.

SOURCE+P_STATEMENTS-TCOL(1) = ' '.

MODIFY SOURCE INDEX P_STATEMENTS-TROW.

ENDIF.

ENDLOOP.

Remove the tokens

LOOP AT P_TOKENS.

I = P_TOKENS-ROW.

J = P_TOKENS-COL.

K = P_TOKENS-LEN - 1.

L = J + K.

DO.

READ TABLE SOURCE INDEX I.

IF L > 72. "Multi line token

L = L - 72.

SOURCE+J(72) = EMPTY.

MODIFY SOURCE INDEX I.

I = I + 1.

K = L. J = 0.

ELSE.

IF L < 72.

K = K + 1.

ENDIF.

SOURCE+J(K) = EMPTY.

MODIFY SOURCE INDEX I.

EXIT.

ENDIF.

ENDDO.

ENDLOOP.

Remove ':' (chain statements)

LOOP AT SOURCE.

CONDENSE SOURCE NO-GAPS.

IF SOURCE(1) = ':'.

DELETE SOURCE.

ENDIF.

ENDLOOP.

Print the result

FORMAT INPUT ON.

LOOP AT SOURCE.

LNUM = LNUM + 10.

IF NOT SOURCE IS INITIAL.

FORMAT INTENSIFIED OFF.FORMAT INVERSE OFF.

TRANSLATE LNUM USING ' 0'.

WRITE /(6) LNUM COLOR 2.

IF SOURCE(1) = '*'.

FORMAT INTENSIFIED ON.

WRITE 8 SOURCE COLOR 6.

FORMAT INTENSIFIED OFF.

ELSE.

WRITE 8 SOURCE COLOR 2.

ENDIF.

ENDLOOP.

Thanks and Regards,

Chandra

Hi,

READ REPORT 'ZDACORPRICERECEIPTS_PRODUCTION' INTO tbl_data.

BREAK-POINT.

SCAN ABAP-SOURCE tbl_data

TOKENS INTO tbl_tk

STATEMENTS INTO tbl_stm

KEYWORDS FROM tbl_kw.

but in sap documentation thru tcode saphelp we can see the following.

SCAN ABAP-SOURCE itab1 ... TOKENS INTO itab2

...STATEMENTS INTO itab3.

... WITH COMMENTS

Effect

Returns comments also, with each individual comment representing a token.

Note

The addition ... WITH COMMENTS is unfortunately not supported at present!
