Comman Control Statements

[Former Member]

HI! Friends,

I hop u guys learn CO, CN, CA, NA....... comparing statements.

If 'ABCD' CN 'ABC'.

write:/ sy-fdpos.

the condition is true and according to that sy-fdpos contains 1st char(V1) in V2. where V1=ABCD and V2=ABC.

Why the value of sy-fdpos comes to 3? Explain.

regards.

Hi,

The logical expression

<f1> CN <f2>

is true if <f1> does also contains characters other than those in <f2>. The comparison is case-sensitive. Trailing blanks are included. If the comparison is true, the system field SY-FDPOS contains the offset of the first character of <f1> that does not also occur in <f2>. If it is false, SY-FDPOS contains the length of <f1>.

Please check this link for more detail and sample codes.

HI,

If STR1 CN STR2.

write:/ sy-fdpos.

endif.

FDPOS will give the number characters(inSTR1) successfully found as a same string in ur search string(STR2).

HI!

I got ur point. according to u, sy-fdpos will give the number characters(inSTR1) successfully found as a same string in ur search string(STR2). But, according to the book if condition is true, sy-fdpos contains 1st char(STR1) in STR2. what that mean?
