3278 Host Key Names

The key equivalents described in the following table are for use with the TYPE and TYPESEC commands. There are 87 keys on the real 3278 keyboard; the following four of them, however, are not accessible from a virtual keyboard:

Keys that are the same on a PC keyboard and a 3278 keyboard (alphanumeric keys and some symbols) are accessed as usual.

The others are accessed through the HOSTKEYS command, which defines about 160 OPS/REXX variables to simulate the 3278 keyings a PC keyboard does not duplicate. Each variable consists of an exclamation point (!) followed by a variable name describing the host key. Thus, !A has not been assigned by HOSTKEYS (key A as usual), but !ALT_A has been assigned.
