Hi Philip,
Is the above exactly what you have written? If so, there is a mixup
in the type of block. The IF should be a FOR, for a loop. If you are
writing an IF block, then the Do should be a THEN and the ENDFOR should be an
ENDIF, and there should be some conditional statement, not I=0,N. I use IDL
but am pretty sure that the formats of the blocks are the same.
