Application Library Subroutines

C–5

PENDING% TRUE if Send will result in a pause.

This should be checked before any Send, to prevent pauses in execution.

WHILE PENDING%

. . .

WEND

Send Sends a record directly to the host.

A string is sent to the host from this terminal. You should test ONLINE%

and PENDING% if you don’t want this to pause.

Send s$

SendQue Sends a record indirectly to the host through the que.

A string is placed into the network queue. The record will in turn be sent to

the host as soon as possible. SendQue has a lower priority than Send, and

will buffer records even when NOT ONLINE.

This subroutine uses the “Host” device, NOT the “Que” device. See “Host

Device” discussion.

Pause will occur if the unit was not ONLINE% and MEMFULL%.

SendQue s$

SetLED Turns a workstation keyboard LED on or off.

A workstation has up to 10 LEDs. The LEDs are numbered 1 to 10. state%

should be TRUE for ON and FALSE for OFF.

SetLED n%, state%

GetTIME$ Translates TIME$ into standard form (HH:MM:SS).

In A-B VBASIC TIME$ is in the form hhmmsshh. This routine drops the

hundreth seconds and puts colons between hours/minutes and

minute/seconds.

GetTIME$

GetDATE$ Translates DATE$ into standard form (MM/DD/YYYY).

In A-B VBASIC DATE$ is in the form yymmddx. This routine ignores the

day (the x).

GetDATE$

1 2 ... 68 69 70 71 72 73 74 75 76 77 78 ... 83 84
