With execstr(), it works! The statement L="iiiiiiiii a very 
2800-chars-long string ....iiiii"
stored into a file read with mgetl() and executed with execstr() is 
actually well done.
Interesting trick!

[By the way, the case from Séverine has an assignment and can be 
processed only with execstr().
Neither eval() nor evstr() can process assignments].
