I would like to use logcat for debugging.  How can I output text to
the android system log?

Thanks.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i const     
ANDROID_LOG_UNKNOWN=0;      ANDROID_LOG_DEFAULT=1;     
ANDROID_LOG_VERBOSE=2;      ANDROID_LOG_DEBUG=3;     
ANDROID_LOG_INFO=4;      ANDROID_LOG_WARN=5;     
ANDROID_LOG_ERROR=6;      ANDROID_LOG_FATAL=7;

Thank you sir.  Based on your answer I found the system log call for
android defined in two places:

LAMW: .../lazandroidmodulewizard/android_bridges/And_log_h.pas

  See also example code for LAMW log:
    (near bottom of file:  "3.1.1. File 1 - "And_log_h.pas" - the
header interface file")
