	Maybe we have to use my patch with some other directives ($config and
$if for example). Indeed, following example doesn't work as expected :

.param ac=0
.options method=gear reltol=1m minbreak=200ps
.if (ac==1)
.ac dec 1000 1 1MEG
.control
    run
.endc
.else
.tran 1u 100m 0 1u
.control
    write results.raw
    run
    fourier 1k v("/VS+")
    fourier 1k v("/VS-")
    quit
.endc
.endif

	Both .control/.endc blocks are run  by ngspice. That's being said only
.tran is reached ;-)

	Best regards,
