Conditional define in execline

[Gorka Lertxundi]

Hi,

Is there an elegant way to achieve a conditional define? something like
this:

if (test)
 A = 0
else
 A = 1

do something with A :-)

More or less this is what I tried, and it works:

export fn "\
ifelse { test }
{
  define A 0
  \\$@
}
define A 1
\\$@"

execlineb -S0 -c ${fn}
s6-echo ${A}

But...I firmly believe that there is a much more elegant way to do this!

Thanks,
