b) complex marker{A341j } : letter i{94a } symbol. {Example:
}
aa) The modes which are output (input) compatible with a 'complex' pattern are those specified by {L} COMPL , {L} REAL and {L} INT (by REF {L} COMPL).
bb) A value V is converted to a string S using a 'complex' pattern P as follows:
· if necessary, V is widened to a complex number;
· the element of S controlled by the "i" frame of P is "^";
· the part of S controlled by the first (second) 'real' pattern of P is that obtained by converting the first (second) field of V to a string using the first (second) 'real' pattern of P {10.3.4.3.1.bb }
· if either conversion is unsuccessful, the conversion of V is unsuccessful.
cc) A string is converted to a complex value C suitable for a name N, using a 'complex' pattern P, as follows:
· the part of the string controlled by the first (second) 'real' pattern of P is converted to a suitable real number {10.3.4.3.1.cc }, which then forms the first (second) field of C.
· if either conversion
is unsuccessful, the conversion to C is unsuccessful.}
