Reading

The @OPEN statement (format 1) can be used to read a file into the current work file for processing or to create a new file. The file remains open until it is closed with @CLOSE.

The @COPY statement (format 1) can also be used to read a file into the current work file. After being read in, the file is closed again.

When ISAM files are read, the KEY operand in the @OPEN or @COPY statement can be used to determine whether the ISAM key is to be ignored or to be taken over as a line number or into the data area.

A file can be run as a procedure by means of the @INPUT statement (format 1).
