[Gretl-users] "*.show" command within if...endif

Dear All I occasionally found that the following script responds an error. It seems that "show" command is not consistent with the "If" condition. It works well when I change to "scalar plot=1." I can replicate this in gretl 1.9.12 under XP and gretl 1.9.12cvs under ubuntu 10.04. Thanks.
