*Extract gain and phase at 1Hz as a complex number.

Simulations” on page 841, and the fprint function for more information on the concepts used in
the example.

Strings
Case-sensitivity of strings (for comparison operators) is set through a global option (.option
set_eldo_cl_string_comparison_case_sensitive=1). Strings are case-insensitive by default, and
it is recommended that this is left unchanged to ensure compatibility.
Tip
See “.OPTION SET_ELDO_CL_STRING_COMPARISON_CASE_SENSITIVE” in the
Eldo Reference Manual.
String variables are manipulated with simple operators. The == and != operators can be used to
test equality or inequality of two strings. The < and > operators are used to test the lexical
ordering of two strings, based on the alphabetical order. For example:
set s_ok = "success" s_fail = "failed" s_code1 = "" s_code2 = "whatever"
