READ - internal

The READ statement can be used to input data from internal files. When used for this purpose, the specifiers associated with it are as follows:

UNIT= <string>
<string> is a character variable. The keyword and equals sign are optional if it is the first item in the list.

FMT= <string, label or *>
Specifies the format in which the data will be read. The keyword and equals sign are optional if this is the second item in the list of specifiers.

IOSTAT= <variable>
<variable> will contain zero if the operation was successful, otherwise a positive value to indicate an error, -1 to indicate EOF or -2 to indicate EOR.

ERR= <label>
<label> specifies a label to go to in the event of an error.

END= <label>
<label> specifies a label to go to on end of file.
