<div>Thanks for your reply.</div>
<div>The program returns -1 after putting a print*,iarg before the if<br>statement. We also found that actually neither of the gtfnam.F in lapw0<br>and lapw1 did work. The program always returns -1 when running the<br>
scripts run_lapw or x lapw1.<br>Is there any other possible solutions? I appreciate your help!!</div>
