2 strscan - scan a string for possible assignment to variables
5 strscan(str, x_1, x_2, ..., x_n)
14 Successive fields of str separated by white space are read and
15 evaluated so long as values remain in the x_i arguments; when the
16 x_i corresponding to the field is an lvalue the value obtained for the
17 i-th field is assigned to x_i.
19 The function returns the number of fields evaluated.
23 ; strscan(" 2+3 a^2 print(b)", a, b, 0);
30 The number of arguments is not to exceed 1024.
