The HelpDflt BRConfig.sys specification indicates the help topic keyword and file names that are to be referenced whenever Ctrl-Y is pressed during program processing. It also establishes the default file name for the HELP$ function.
Comments and Examples
The HELPDFLT specification takes effect only when a program is running. The indicated topic keyword and file names are accessed when the <HELP> key is pressed during RUN mode. The file name specified is also accessed when <HELP> is pressed during INPUT mode, unless the programmer has overridden the default file name in HELP$.
"Keyword" is the topic name that has been assigned to the menu or text that is to appear when Ctrl-Y is pressed.
"Filename" is the name of the help text file within which the keyword can be found.
There is no default file name established for help when a program is running. The file name parameter becomes required in the HELP$ function. Pressing the <HELP> key (except during INPUT mode) will have no effect on a running program because ON HELP SYSTEM operates as ON HELP IGNORE.
The CONFIG command can be used during program execution to override the BRConfig.sys file's HELPDFLT specification.
- The HELP file search now uses the following directory sequence
|- Current Directory|
|- Base Node of First Drive Statement (where second param points)|
|- BR Starting Directory Note that the HELPDFLT statement refers to filename not dirname.|
