Operation
A CTRL Y entered during conversion displays the number of records successfully converted,
and conversion continues. On variable length data files, if a field or portion of a field is
beyond the length of the record just read, a warning is displayed and that field is not
converted on that record. Other fields on the same record are converted, and processing
continues with subsequent records. After each file has been converted, the user is
prompted for another file name.
In addition to the text and data options, there is a test conversion option which shows how
the conversion algorithm operates. The test conversion option must be run from a terminal
configured for 7-bit operation with the chosen national substitution set. The user is
instructed to enter a string, and the result of the conversion is displayed. The user does not
have to switch back and forth between 7-bit and 8-bit operation to see the result. Each
character converted is displayed as a decimal value in parentheses rather than
graphically. Other characters are displayed unchanged.
At any point in the program, a
Return exits the current program level. A Return in response
to a request for the starting position and length of a field in a data file indicates that the
definition of fields is complete, and the program proceeds with the conversion of the data
file. A
Return entered in response to a request for a text file name indicates the conversion
of text files is complete; the program goes back to the question: "Type of file to be
converted?".
