  • This line was added.
  • This line was removed.
  • Formatting was changed.

If the HELP key or the HELP function key is pressed at any time while executing a user-written LANSA process or function and the screen cursor is NOT on the same line as a message then user-written HELP text associated with the process, function, or fields used by the function can be reviewed.

If the user is a LANSA developer, then both user-written technical and user HELP text will be displayed. Otherwise, only user-written user HELP text will be displayed.

  • If the process main menu was on the screen then the HELP text associated with the process will be displayed initially.
  • If a function screen format (resulting from an RDML DISPLAY or REQUEST command) was on the screen and the cursor was within the boundaries of a field on the screen, then the HELP text associated with the field will be displayed initially. The phrase "within the boundaries" means within the field itself or anywhere on its associated label, description, or column headings.
  • If a function screen format was on the screen and the cursor was not within the boundaries of a field, then the HELP text associated with the function will be displayed initially.

Note
Note: The user-defined process level HELP text overlays the lower portion of the process menu in a "window". The advantage of the window over a full screen presentation is that it visually reminds the user what he/she was doing when the HELP function key was used.

While the HELP text window is on display you can only work with the facilities available within in it, these include:

  • Invoke the extended HELP facility. Use the function keyed identified as "Ex HELP". Normally this function key is only available when reviewing the HELP text associated with a field. If used, the HELP text associated with the current process or function will be displayed.
  • Exit from the HELP facility and return to what was being done when the HELP key was first used. To do this use the function key identified as "Exit".
  • Cancel what is being done at the moment and return to what was being done previously. To do this use the function key identified as "Cancel".
  • Cause the current process's HELP Index to be displayed. To do this use the function key identified as "Index".
