SUMMARY
In Windows Help macros, strings may be delimited in two ways. The
string can be opened and closed by double quotation marks or the
string can be opened by a single opening quotation mark and closed by
a single closing quotation mark.
Any quoted strings contained in a string delimited with double
quotation marks must be enclosed in opening and closing single
quotation marks.
The single opening quotation mark is different from the single closing
quotation mark. The single opening quotation mark (`) is paired with
the tilde (~) above the TAB key on extended keyboards; the single
closing quotation mark (') is the same as the apostrophe. For example,
CreateButton("time_btn", "&Time", "ExecProgram("clock", 0)")
is illegal because the string "clock" uses double quotation marks
within the double quotation marks used for the ExecProgram macro. The
following example corrects the error by enclosing "clock" in single
quotation marks:
CreateButton("time_btn", "&Time", "ExecProgram(`clock', 0)")
