Chapter 6 - Programming Input Commands Display data stream commands form two categories: the input commands and the output commands. The IBM 5250 Information Display System Functions Reference Manual (IBM part number SA21-9247-6 provides more detailed descriptions than those presented in this guide). These are the input and output commands and hex codes with additional reference information about each command. Input and output commands and hex codes Input Commands Hex Code Reference Read Immediate 72 See"Read Immediate" on page 211 Read Modified Immediate 83 See "Read Modified Immediate Alternate" on Alternate page 212 Read Input Fields 42 See "Read Input Fields" on page 213 Read MDT Fields 52 See "Read MDT Fields" on page 214 Read MDT Alternate 82 See "Read MDT Alternates" on page 215 Read Screen 62 See "Read Screen (Immediate)" on page 216 Save Screen 02 See "Save Screen (Immediate)" on page 216 Write Structured Field f3 See "Write Structured Field" on page 217 Clear Format Table 50 See "Clear Format Table" on page 219 Clear Unit 40 See "Clear Unit" on page 220 Clear Unit Alternate 20 See "Clear Unit Alternate" on page 220 Restore Screen 12 See "Restore Screen" on page 221 Roll 23 See "Roll" on page 222 Write Error Code 21 See "Write Error Code" on page 223 Write to Display (WTD) 11 See "Write to Display (WTD)" on page 224 Input commands consist of immediate and AID-associated Read commands. Immediate commands are executed when the controller receives the command. AID-associated commands are queued until the operator presses an AID-generating key such as Enter/Rec Adv. Other AID-generating keys are listed in the chapter for each computer. Read Immediate The Read Immediate command is similar to the Read Screen command, except the data comes from the format table rather than the display. The command sends back the contents of all the input fields on the display. TE 2000TM Terminal Emulation Programmer's Guide 211
