How to execute FOR loop in robot file?

val = 12

:FOR    ${i}    IN RANGE   ${val}
Run Keyword If  condition1 or condition2  Call_Keyword  ${val1}  {val2}
Run Keyword If  condition3  exit for loop

I am using this snippet test.robot file, but it says as

FOR loop contains no keywords.

I do not understand. what's wrong in this ?

You forgot to indent the keywords in the loop, e.g. to mark them as "the looped over block".
As explained in the user guide,

The keywords used in the for loop are on the following rows and they must be indented one cell to the right. When using the plain text format, the indented cells must be escaped with a backslash, ...

So in your case, as of 2017, it should be:

:FOR    ${i}    IN RANGE   ${val}
\        Run Keyword If  condition1 or condition2  Call_Keyword  ${val1}  {val2}
\        Run Keyword If  condition3  exit for loop

In the newer version of the framework this syntax is deprecated, and uses a block ended with the END keyword:

FOR    ${i}    IN RANGE   ${val}
        Run Keyword If  condition1 or condition2  Call_Keyword  ${val1}  {val2}
        Run Keyword If  condition3  exit for loop
END

According to the user guide, a correct for-in-range loop in Robot Framework 3.2+ would be the following:

FOR    ${i}    IN RANGE   ${val}
    Run Keyword If    condition1 or condition2    Call_Keyword    ${val1}    {val2}
    Run Keyword If    condition3    exit for loop
END

${endvalue}    Set Variable    12    #    End Value

${Step}    Set Variable    1    #    step value

:FOR    ${i}    IN RANGE    ${startvalue}    ${endvalue}    step=${step}

\        Run Keyword If  condition1 or condition2  Call_Keyword  ${val1}  {val2}
\        Run Keyword If  condition3  exit for loop
