Byte Group 10The type of format specification in each byte group in the control string is identifiedby the first byte of the group as follows:ee•1 = This is the last byte of the group.41 = Return control to the object code program. 300 = Field is neither right-adjust nor field exit required.01 = Field is right-adjust, alphabetic filLl10 = Field is field exit required.11 = Field is right-adjust, numeric filLlCD 0000 = Field is picture check field. 10001 = Field is alphabetic.0010 = Field is numeric.0011 = Field is hex.0100 = Field is Katakana.0101 = Format level zero.0110 = Fixed position prompt.0111 = Standard prompt or constant insert data.1000 = Invalid specification. 21001 = Field is alphabetic only.1010 = Field is numeric only.1011 = Field is digits only.1100 = Field is Katakana only.1101 = Invalid specification. 21110= Display attribute.1111 = Control specification (see Control Byte Group).llf picture check is specified, the field cannot be right-adjust or processed right to left.2Bit values 1000 and 1101 cause external status for invalid format control string to be posted.3 1f bit 1 is on, the keyboard/display microprocessor returns control to the object code program.When the control string is processed forward, control returns after the format group is processed.When the control string is processed backward (a backspace key was pressed), control returnsbefore the format group is processed.4 Bit 0 of each byte in the control string indicates whether th is byte is the last byte of a group.Main Storage Data Areas 101
