Hi all! ;-)

I'm trying to pipe a cgm from a ncarg script (f77) into ctrans.
Following the manual
(http://ngwww.ucar.edu/ngdoc/ng/fund/chp6-10/workstations.html) I set
the NCARG_GKS_OUTPUT variable to "|ctrans", but no matter what/if I set
GRAPHCAP when I try to open a workstation with this piece of code

      CALL GOPKS (IERRF, ISZDM)
      CALL GOPWK (IWKID, LUNIT, IWTYPE)
      CALL GQOPS (OPSTA)
       print *, 'After COPWK ',OPSTA
      CALL GACWK (IWKID)
      CALL GQOPS (OPSTA)
      print *, 'After GACWK ',OPSTA

where IERRF = 6, ISZDM = 0, IWKID = 1, LUNIT=2 and IWTYPE=1
I get this output:

Error in flswks_() : Seek failed
 GKS ERROR NUMBER 304 ISSUED FROM SUBROUTINE GOPWK :
 --INPUT/OUTPUT ERROR HAS OCCURRED WHILE SENDING DATA TO A WORKSTATION
 After COPWK 2
 GKS ERROR NUMBER 25 ISSUED FROM SUBROUTINE GACWK :
 --SPECIFIED WORKSTATION IS NOT OPEN
 After GACWK 2
 GKS ERROR NUMBER 25 ISSUED FROM SUBROUTINE GSCR :
 --SPECIFIED WORKSTATION IS NOT OPEN

Instead if I don't set none of env variable it runs fine producing a gmeta
file.

any clue?

thanks in advance
