TWAIT/LWAIT/NWAIT
Determine the characteristics of a wait period. Applies to Wait (4) and Get Key(51).
Session Option Description
TWAIT For Wait (4), wait up to 60 seconds before timing out on XCLOCK
or XSYSTEM. For Get Key (function 51), wait until a keystroke is
queued before returning. TWAIT is the default setting.
LWAIT For Wait (4), wait until the XCLOCK or XSYSTEM clears. This
setting is not recommended because your Windows HLLAPI does
not regain control until the Host is available. For Get Key (51), wait
until a keystroke is queued before returning.
NWAIT No wait period applies. Wait (4) and Get Key (51) calls each check
their respective status and return immediately.
TRON/TROFF
Determine whether to enable or disable Windows HLLAPI tracing. The information in the trace is
intended to help debug a Windows HLLAPI program. Tracing is turned off when the Windows
HLLAPI program ends or when TROFF is specified.
Session Option Description
TROFF Turn tracing off.
TRON Turn tracing on. With tracing enabled, all executed Windows
HLLAPI functions are traced.
EAB/NOEAB
Determine whether to include extended attributes (EABs) or not. Applies to Copy Presentation Space
(5), Copy Presentation Space to String (8), Copy String to Presentation Space (15), Copy String to
Field (33) and Copy Field to String (34).
Session Option Description
EAB Include extended attributes (EABs) with Data String. Since there is
an EAB for every character that displays, you must define Data
String to be twice the size of the Host session presentation space or
field.
NOEAB Do not include any extended attributes (EABs) with Data String (no
EABs). This is the default setting.
