Gcode parser error?

Alan

I am attempting to read a simple G code file.  It is legal G code:  I'm running Marlin on a RAMPS 1.4 board. 

G1 F1000 X-.333 S27
X-.333 S35
X-.333 S12
X-.333 S25

You'll notice that only the G1 is only in the first line.  G1 is modal, and should be "carried over" to subsequent lines. 
I get "unrecognized code".   Even a simple file might have 1000 blocks, making it very difficult to edit manually.  Is there a parameter that can be set? 

I prefer to have the G1 etc. codes on each line.  However LaserGRPL generates them that way. 

I've also noted that Marlin wants all caps.

Thanks,
Alan

Also this is for marlin and this is repetier forum, the code is illegal. Printer firmwares have no sticky Gx/Mx and you need to add it for every line.

Thanks,
I'm slowly working my way through Marlin.  It doesn't like my line numbers either.
