demonstration programs merely print the text of the card to the screen (after peeling off the status
information) through the COBOL statement "DISPLAY COLS, CARD-EOL" or the BASIC
statement "PRINT MID$(A$,3,L)". (Use of disk files will require the addition of a file description
(FD) section in COBOL and OPEN, FIELD, etc. statements in BASIC. Refer to the COBOL or
BASIC language manual for details.)
If your application uses a special format card, you'll need to make some changes to the BASIC and
COBOL programs. In the COBOL program, you'll need to change the 77 level descriptions and
the 01 CARD descriptions in the Working-Storage section of the Data Division. In the BASIC
program, you'll need to change the defined value of "CL" (card length). Also, see Chapter 4 of this
manual for details on special formats that the CR-S10 will read.
