I/O formatting
Chapter 9236
transferring data between machines with different machine representations for a data type.
I/O formatting can be implicit or explicit. Implicit formatting occurs during list-directed and
namelist-directed I/O: data is converted without programmer intervention, based on the data
types of the I/O list items; see “List-directed I/O” on page 210 and “Namelist-directed I/O” on
page 213. Explicit formatting occurs under the control of the programmer, who specifies how
the data is to be converted.
This chapter describes explicit I/O formatting and includes information about the following:
• FORMAT statement
• Format specification
• Edit descriptors
• Embedded format specification
• Nested format specifications
• Format specification and I/O data list
