Standard: F77 F90 F95 F2003
SIZE = variable

The SIZE= specifier may appear only as a ci-spec in a formatted READ statement that also has the ADVANCE='NO' specifier.

The variable shall be a scalar Integer.
The SIZE= specifier sets the variable to the number of characters transferred by data edit descriptors during execution of the READ statement. This is most useful in conjunction with the EOR= specifier.
