Mapping values for the APL2 character set

This topic lists the GDDMXD/MVS default mapping values for the APL2® character set. However, If the hlq.GDXAPLCS.MAP data set exists, the default mapping values are overridden.

Each entry in the hlq.GDXAPLCS.MAP data set (alternative character set) contains the mapping for a particular physical key that corresponds to three characters. The characters correspond to the physical key by:

Pressing the key alone
Pressing the key and the Shift key simultaneously
Pressing the key and the Alt key simultaneously

The hlq.GDXAPLCS.MAP data set entries must contain the following seven single-byte hexadecimal values entered as EBCDIC characters:

Value 1 is the hexadecimal keycode for the physical key.
Values 2, 4, and 6 identify whether the character is in the primary or alternative character set for the emulated 3179G. If the character is in the primary set, the value is 0; if the character is in the alternative set, the value is 8.
Values 3, 5, and 7 specify the EBCDIC code of the character in the character set.

The combination of values 2 and 3 define the bytes that describe the character when the key corresponding to the keycode is pressed alone.

The combination of values 4 and 5 define the bytes that describe the character when the key corresponding to the keycode and the Shift key are pressed simultaneously.

The combination of values 6 and 7 define the bytes that describe the character when the key corresponding to the keycode and the Alt key are pressed simultaneously.

Table 1 lists the mapping values for the APL2 character set.
