CHAPTER 4 PROGRAMMABLE FUNCTION STRINGS

Overview

The 5250 ALLY has a total PFS storage of 20K bytes. Programmable Function Strings (PFSs) are used by the AGILE 5250 ALLY to control all functions that vary from printer to printer. Whenever some special formatting or control function is required, the 5250 ALLY looks up the appropriate PFS and sends it to the printer. For example, if the System requests emphasized printing, the 5250 ALLY looks up and sends PFS 23

— BOLD ON.

The 5250 ALLY will load the appropriate PFSs for the printer when the configuration for the printer is loaded. If the printer is among the listed printer configurations, the user will probably not have to make any modifications to the PFSs. If the output device is not listed among the supported printer configurations, the user either will have to define a set of PFSs or modify an existing set as part of the output port configuration. By changing or defining PFSs, almost any printer can be driven by the 5250 ALLY.

If the user would like to use the PFSs in a way not anticipated by AGILE, the user can modify them with commands in the twinax or alternate host data stream. For example, if the printer can double underline, and if the user would like to configure the 5250 ALLY to double underline instead of single underline, enter the appropriate control string into PFS 27 — UNDL ON. The user also will have to enter into PFS 28 — UNDLOFF the appropriate control string that turns off double underlining.

PFSs can also be used to send printable characters to the printer. Printable characters must be entered between quote marks (") to distinguish them from hexadecimal codes.

PFSs in the 5250 ALLY are entered as a string of hexadecimal or printable ASCII characters. Most printer reference manuals have examples of control strings in hexadecimal, and this makes it easy to enter them directly into the 5250 ALLY as PFSs.
