input
The dataset name. The name should be enclosed in quotes if it
contains any of the following: blank, comma, colon, quote, equal
sign.
This means in practice that the quotes are required on a Vax for
all dataset access outside the home disk. On VM/CMS, the blanks
between file-name and file-type (and perhaps file-mode) may be
replaced by dots, thus avoiding the need to add the quotes.
Double quotes should be used when case is important, e.g. on
Unix systems.
A string of up to 80 characters.
If this string is found at the start of a line in the input file,
the file is closed and reading continues from the previously opened
file.
Specifying EOF as label implies the file is read until the end of
the physical file.
["EOF" is default]
