Mode-Sensitive Key Assignments   (details) 48 ENG   2KB/1KB
Key assignments can serve double purpose. For example, I never use the MATRIX WRITER application key, except to put DUP into programs. But I use ASN regularly. So I assigned the following little program to the MATRIX key. Its action depends on what mode the 48's in. When the 48 is in program entry mode (PRG annunciator on), then this program generates a DUP; otherwise, it does ASN (instead of the Matrix Writer).

STR22 3.1   (details) 48 ENG   2KB/1KB
This small program formats text to fit within the 22-character wide display. The way it does it, however, is different than other similar programs. A machine code routine simply rearranges the space and linefeed characters in two passes. The first pass simply replaces all linefeeds with spaces. The second pass puts a linefeed at the first space encountered backwards from the 23rd character of each line. As a result, words do not get haphazardly split and the program is extremely fast. Also includes versions that split at 24 characters (for printing to the 82240B infrared printer), 33 characters (for Jazz's ED, TED, and VV), and 80 characters. For both the S and G series.
