Q68678: Help Files for QuickC Require Special "Backtrace" Declaration

When creating a help file using the Microsoft Helpmake utility, !B is
defined to have the effect of backtracing to the previous help screen
(if available). However, this is true only when using QuickHelp or the
Programmer's WorkBench (PWB). If an attempt is made to use this help
file with QuickC, the link will issue a beep and no backtrace will be
allowed.

The documentation included with Microsoft C version 6.00 does not
reference the exclamation (!) character as being a special function.
However, on pages 20-21, the "Professional Advisor Library Reference"
lists all the options available for this command. It also states that
the !CQ.HB command will allow QuickC version 2.00 compatibility.
However, it should be noted that the compatibility for this function
is for QuickC version 2.50 as well. The use of this command gives
complete compatibility through C versions 6.00 and 6.00a, as well as
QuickC versions 2.50 and 2.00.

Another error in the documentation is that !CQ.HB must be in all
lowercase letters (that is, !cq.hb). HelpMake will not issue an error
message with an uppercase command, but it will also not allow a
backtrace to be performed.
