CCTYPE Differences                  

Question: I am using ACIF to generate an AFPDS file from line data files, created with legacy applications, that use either machine carriage controls or ANSI carriage controls. I know that the carriage control types are similar in their functions, but I would like to know the main differences. What determines when I should select CCTYPE=A, CCTYPE=M, or CCTYPE=Z?

Answer: ANSI carriage control is the most widely used carriage control type and is represented by a single character occurring as the first character of a print record.

ANSI carriage controls:

·        SPACE is used for: Single space the line and print

·        0 is used for: Double space the line and print

·        - is used for: Triple space the line and print

·        + is used for: Don’t space the line and print

·        1 is used for: Skip to channel 1 (Top of Form)

·        2–9 is used for: Skip to a position on the page (usually hardware-defined)

·        A,B,C is used for: Defining a vertical tab record or FCB

Note: All ANSI carriage controls perform any defined spacing movement prior to printing the line.

CCTYPE=A is used to interpret ANSI controls in EBCDIC.

CCTYPE=Z is used to interpret ANSI controls in ASCII.

Machine carriage controls:

·        X'09' is used for: Print the line and single space

·        X'11' is used for: Print the line and double space

·        X'19' is used for: Print the line and triple space

·        X'01' is used for: Print the line and don’t space

·        X'0B' is used for: Space one line immediately

·        X'89' is used for: Print the line, then skip to Top of Form

·        X'8B' is used for: Skip to Top of Form immediately

Note that machine controls perform printing prior to performing any defined spacing movement.

CCTYPE=M is used to interpret machine controls.
