I am not positive what you are asking, but yes run a IDMSRPTS
We use these options:
//SYSLST DD DISP=(NEW,CATLG),
// DSN=IDMS.SHPLUS.&SYSTEM..&VERSION..GLBLCHEM,
// RECFM=FB,LRECL=133,
// SPACE=(133,(30000,3000),RLSE)
//SYSIDMS DD *
LOCAL=ON
//SYSIPT DD *
SCHEMA=(GLBLCHEM) VERSION=(2)
RECDES SETDES
/*
Then down load the file to your PC or a shared network drive as a .txt
cd 'grps/shared/idms/Schema Plus/Help and Diagram Files'
dir
put 'IDMS.SHPLUS.ECL.TEST.GLBLCHEM' 'ECL TEST GLBLCHEM.txt'
quit
Then you can select the file from DRAW.
Ie
Click on File, then Open Schema Report
Select & Open the environment you want
Click the green Plus button;
Enter name you want to call this diagram
Now you can drag and drop:
Good Luck :D
