ANSI carriage control characters

The most universal carriage control is ANSI, which consists of a single character that is a prefix for the print line. The standard ANSI characters are:

ANSI Action
space Single space the line and print
0 Double space the line and print
- Triple space the line and print
+ Do not space the line and print
1 Skip to channel 1 (the top of the form, by convention)
2-9 Skip to a hardware-defined position on the page
A,B,C Defined by a vertical tab record or forms control buffer (FCB)
All ANSI control characters perform the required spacing before the line prints. Using line2afp command keywords and values, ANSI controls can be encoded in EBCDIC (cctype=a) or in ASCII (cctype=z).
