APPENDIX B SCS/DCA COMMAND SUMMARY
Overview
The AGILE 5250 OPTIMA, like the IBM printers it emulates, accepts SCS (SNA Control String) and DCA - FFT (Document Content Architecture - Final Form Text) commands. These commands control formatting of the text and other printer functions.
The OPTIMA’s IBM printer emulation uses the FMTINFO: and
PFSINFO: settings for the output port to simulate the appropriate behavior on the output device (usually a printer).
The OPTIMA supports most of the commands that are available on any of the IBM printers it emulates. These commands are not limited to the emulations of the IBM printers that normally use those commands, but are available in all of the IBM printer emulations. For example, the OPTIMA supports the DCA command, Justify Text Field, not only when it is emulating a 5219 or 3812 (IBM printers that support that command), but also when it is emulating a 5225 (an IBM printer that does not support that command). This means that the OPTIMA implements the full command set listed here regardless of the IBM printer emulation for which it is configured.
This section lists the SCS and DCA commands that the OPTIMA implements and also gives some information about the methods it uses in emulating the IBM printer.
Note: All variables are entered as hexadecimal (base 16) values. The parameter nn represents a count byte equal to the number of bytes following the count byte plus the count byte itself, except where otherwise specified.
