The CHART keyword creates a sequential data set in the data set referenced by the VMACHART DD statement.

In the GFTAVMAP JCL member, the VMACHART DD is allocated as a SYSOUT file. To override this specification, insert the following DD statement in your GFTAVMA execution input stream following the EXEC GFTAVMA statement:

//VMA.VMACHART DD DSN=your.data.set, DISP=(NEW,CATLG),
//   DCB=(LRECL=80,RECFM=FB), SPACE=(TRK, (1,1))

This statement directs the CHART output to a sequential data set that you can use to create charts using the graphics package of your choice. See Submitting the GFTAVMA JCL for the complete JCL member.
