This compiler error will occur if a for instruction does not contain a step value or expression where expected.

For example:

for nTemp = 1 to 10 step       // step what ?
    // do something    
endfor

Note that completely omitting the step keyword and step value (as in the example below) is allowed. In that case, the compiler assumes that the step value is 1 (one).

for nTemp = 1 to 10 // compiler assumes step=1
    // do something    
endfor

For more details, see looping with the for keyword.
