Constant Insert Data and PromptsConstant insert format groups specify the ioeation and the iength of constant insertdata to be moved to the screen and inserted into the current record buffer. Promptformat groups specify the length and location of a prompt to be moved to thescreen fixed prompt line or to current screen position. Following are the controlstring specifications for constant insert and prompts:Byte Group 101 = Last byte of the group.Ie 0110 = Fixed position prompt.0111 = Standard prompt or constant insert.o Index into the system table for prompts, where the address of the prompt isstored if the index is less than 126; otherwise this byte is 7F and the index isspecified in the following 2 bytes. For constant inserts, this byte must be 7F.2If this byte is xxOOOOOO, the fixed prompt line is cleared. 1• 1 = Specification is for constant insert data.o = Specification is for prompt.• If the previous byte is 7F, these bits specify the index into the system table,where the address of the constant insert or prompt is stored.• Length minus 1 of the constant insert or prompt if the length is less than 128;otherwise, this byte is 7F and the length minus 1 is specified by the following2 bytes. lo If the previous byte is 7 F, these bits specify the length minus 1.1llf clear the fixed prompt line is specified, the prompt line is cleared (the number of positionsspecified in the length bytes of the format group) beginning with the first position of the line. If thelength is not specified in the format group, the full line is cleared.21f the constant insert or prompt is stored within the partition, the address of the system table is inbytes hex 00 and OE (address hex 80 and 8E relative to the start of the partition) of the keyboard/display lOB. If the constant insert or prompt is stored within the common area, the address of thesystem table is in bytes hex FE and FF of the system control block.110
Display AttributesA display attribute format specification consists of 2 bytes, the format identifierand a display attribute byte, as shown below. The display attribute is moved to thescreen at the current screen position.ByteI Gro.up IDI11111110'~'1,,~~ ~elf 111, display is inhibited." 1 = Last byte in the group.e Not used.• 1= Column separators displayed.CDG1 = Blink.1 = Underline.o 1 = High intensity.CD1 = Reverse image.EDIT FORMAT CONTROL STRINGSControl information and field descriptions are specified by groups of bytes in anedit format control string. The order in which the control string is assembled is theorder in which the string is processed. The following diagram is a general descriptionof an edit format control string. Following this general description is a descriptionof each type of specification that can be in the control string.Main Storage Data Areas 111
