[SOLVED] LNAME - exctracting variables from stringed expression?

[Didier Lachieze]

You can also do:

Code:

LNAME(EXPR("'"+L1(1)+"'"))

In your case, with L1(1):="(C-A)", it will return {C,A}

If you have to use it several times it may be interesting to create a small function such as:

Code:

EXPORT STR2EXPR(str)
BEGIN
RETURN EXPR("'"+str+"'");
END;

and just do: LNAME(STR2EXPR(L1(1)))
