Accessing PPPL's TRANSP data in MDSplus via Fortran

Subroutines

TRPROFIL
reads in a specified function of time and another coordinate as well as the associated times, label and units from a TRANSP run.
TRSCALAR
reads in a specified scalar function and associated times, label and units from a TRANSP run.

Encoding of MDSplus specifications in calling arguments

Server name, Tree name and Pulse number are encoded in the standard calling arguments "DISK", "DIR" and "RUNID".

e.g. for PPPL's TRANSP:
     DISK  = 'MDS+-TRANSPGRID.PPPL.GOV@TRANSP'
     DIR   =  'JET.99'
     RUNID =  '46982C09'

e.g. for MIT's TRANSP:
     DISK  = 'MDS++cmoda.psfc.mit.edu@TRANSP01'
     DIR   =  ' '     
     RUNID =  '960116024'

At PPPL the MDSplus puls number is usually not known. Runs are known by Tokamak, Year, and Runid.

Following is a detailed outline of the encoding:

DISK:
char  1:4       MDS+
      5:5       +   if RUNID contains MDS pulse number
                -   if MDS pulse number is not supplied
                    in this case DIR must contain TOK.YR
      6:n       <Server name> - e.g. TRANSPGRID.PPPL.GOV
      n+1:n+1   @
      n+2:      <tree name>   - e.g. TRANSP_NSTX
      
      

DIR:
     if DISK(5:5) = '-'  : TOK.YR  e.g. 'TFTR.97', 'JET.99'
                           otherwise not used

                 
RUNID: 
     if DISK(5:5) = '-'  : TRANSP RunID: e.g. 46982C09
     if DISK(5:5) = '+'  : MDSplus pulse number
