MFP language if, elseif, else, endif statements:

If, elseif, else and endif comprise condition block in MFP. They should be used like the following example:

If conditionA

    ......

elseif conditionB

    ......

elseif conditionC

    ......

......

......

......

else

    ......

endif

, where conditionA, conditionB, conditionC, etc. are expressions which have boolean values. If they are not boolean values, MFP converts them to boolean first (if MFP can).
