DOCERR: BEEPQQ and SLEEPQQ Deal in Milliseconds and HzLast reviewed: July 20, 1995Article ID: Q104945 |
The information in this article applies to:
SYMPTOMSThe Microsoft FORTRAN PowerStation "Language Guide" describes the BEEPQQ subroutine on page 214 as follows:
BEEPQQ(duration, frequency) duration (Integer*4; input) Length of the beep in microseconds. frequency (Integer*4; input) Frequency of the tone in KHz.The documentation on SLEEPQQ on page 496 is as follows:
SLEEPQQ(duration) duration (Integer*4; input) The number of microseconds to sleep (delay program execution).The above information is incorrect. The arguments for BEEPQQ are in the wrong order. The duration should be in milliseconds and the frequency in hertz (Hz). The online help for these two run-time subroutines is correct.
RESOLUTIONMake the following modifications on page 214 of your documentation:
BEEPQQ(frequency, duration) frequency (Integer*4; input) Frequency of the tone in Hz. duration (Integer*4; input) Length of the beep in milliseconds. Remarks BEEPQQ does not return before the sound terminates.Similarly, page 496 should be modified to reflect the following:
SLEEPQQ(duration) duration (Integer*4; input) The number of milliseconds to sleep (delay program execution). MORE INFORMATIONThe sample code produces a low, 1-second tone and then sleeps for 1 second.
Sample CodeC No compiler options required include 'flib.fi' include 'flib.fd' print *, 1 call beepqq(262,1000) print *, 2 call sleepqq(1000) print *, 3 end |
