DYNCONV Control Statement Syntax
Apply the following rules when using the DYNCONV control statement:
• The control statement is in free-form format beginning in any statement
position.
• Leave at least one space following the CONVERT command.
• All operands must be separated by one or more blanks.
• Continuation statements are not supported.
This command has the following format:
CONVERT OLDDEV=nnnn NEWDEV=nnnn [SECNO=nnn] [PERCENT=nnn]
CONVERT
OLDDEV=nnnn
Optional command. Converts the number of allocated tracks/blocks to a new
value.
Specifies either the device type, for which the input job stream is set up, or a
device conversion value to be used for the conversion calculations.
For device type values, you can specify 2311, 2314, 3310, 3330, 3340, 3350,
3370, 3375, 3380, 3390 or 9345. For any other FBA devices specify 3370.
Device conversion values can be specified as a 1- to 4-digit number.
NEWDEV=nnnn
PERCENT=nnn
Specifies either the device type on which the output job stream is to be used,
or a conversion constant value to be used for the conversion calculations. You
can use any of the values listed above.
Optional operand. Specifies a percentage of the primary extent allocation that
is to be used for the generated secondary extents.
If the JCL is being converted to operate on a new device type (OLDDEV and
NEWDEV parameters), the calculated percentage is based on the allocation
value of the primary extent after the device conversion calculations have been
performed.
SECNO=nnn
Optional operand. Designates a number of secondary extents to be generated
for each sequential disk file. For SD only, any existing secondary extent
statements are dropped from the output JCL if this parameter is included.
Notes on the DYNCONV Program:
• The input file must be assigned to SYS001.
• The output is directed to SYSPCH.
• Denote the end of the input by including a *END statement in the input job
stream.
