Journal file conditionals based on arguments.
Is it possible to have a GO script with a conditional based on the value of an argument?
The main relevant documentation is in the Ferret Users Guide, see "GO, arguments" in the index.
Also relevant is thedocumentation on the IF-THEN-ELSE structure
The same approach that works on arguments also applies to symbol substitution.
Here's an example jnl file -- test.jnl:
if $1"false|yes>true|*>false" then say "The user told me to do it" else say "The user told me not to do it" endif
The first "false" is the default value if no argument is supplied. "yes" translates to "true", all else ("*") translates to "false".
Used as follows:
yes? cancel mode verify yes? go test yes The user told me to do it yes? go test no The user told me not to do it yes? go test The user told me not to do it
