5. This STCPOST control card indicates that the DEFINE function
;s to define device 790 as ddname SYSUT1 for DD type O.
6. This STCPOST control card indicates that the DEFINE function is to define device 791 as ddname SYSUT2 for DO type O.
7. This STCPOST control card indicates that the FORMAT function is to be executed. The VOlIO parameter specifes that a vol-ume label and VTOC are to be written and that the volvol-ume id
is PAGE01.
8. This STCPOST control card specifies that the subsequent functions are to execute against the device defined by ddname SYSUT2.
9. This STCPOST control card indicates that the FORMAT function
;s to be executed. The VOlID parameter specifes that a vol-ume label and VTDe are to be written and that the volvol-ume id
is PAGE02.
10. This card indicates the end of the job ~Cl deck.
The following example shows how to execute the FORMAT function using the basic DOS ~Cl.
Basic DOS/VSE ~Cl Example
This example uses the basic DOS/VSE JCl to execute the FORMAT function on a 4305 device at address 123.

STCPOST Functions MODECHG MODECHG
The MODECHG function is used to change the format of a 3350 type volume from native mode to compatability mode or from
compatabil-ity mode to native mode.
Function Required Parameters Optional Parameters
MODECHG FORCE
NOTE
MODECHG does not format the volume for use by the oper-ating system (no label or VTaC is created).
Required Parameters
There are no required parameters.
Optional Parameters
FORCE
The FORCE parameter specifies that the operator is not to be asked for confirmation to initialize the device.
Specifying this parameter implies confirmation.
Operation Considerations
The logical volume is formatted in the mode specified by the operating system's Unit Control Block (UCB) or as defined to the
STCPOST Stand-Alone Executive (SAE) during SAE device definition.
All of the tracks are written with the proper Home Address (HA) and Record Zero (RO).
MODECHG does not change any track assignments. All defective pri-mary tracks remain defective with an alternate track assigned.
Defective non-primary tracks become defective alternates.
MODECHG formats all of the CE tracks of a 3350 device in native mode.
• The MODECHG function requires a DO card type O.
• The MODECHG function can not be executed using the STCPOST OS/VS JCL procedure, use the STCPOSTO procedure.
• MODECHG should not be used if the operating system supports 3350 type devices in native mode. Use the appropriate system
STCPOST Funct;ons MODECHG
• MODECHG must be run on both logical volumes if the device is to be formatted in the 3330-1 compatability mode.
Operation Example
The following example shows how to execute the MODECHG function using the basic OS/VS JCL.
This example uses the basic OS/VS JCL to execute the MODECHG function on a 3350 type device at address 285.
