/sys$common/syshlp/helplib.hlb CQUAL Routines, UTIL$CQUAL_CONFIRM_ACT, Description *Conan The Librarian (sorry for the slow response - running on an old VAX) |
UTIL$CQUAL_CONFIRM_ACT prompts the user for confirmation. You must supply at least one prompt string to this routine. If you supply both strings, you should have an expanded and condensed form of the prompt. The condensed form should be supplied through the prompt_string_1 parameter; the expanded form through prompt_ string_2. The prompt string supplied by prompt_string_1 is initially used if the prompt_string_1 is present, does not have a length of zero, and either: o The current_form parameter is not specified o The current_form parameter is specified and contains: - UTIL$K_CQF_SHORT - UTIL$K_CQF_UNSPECIFIED - A value greater than UTIL$K_CQF_MAX_FORM The prompt string supplied by prompt_string_2 is used initially if prompt_string_2 is present, does not have a length of zero, and either: o prompt_string_1 is not present or has a length of zero o The current_form parameter is specified and contains the value UTIL$K_CQF_LONG Once the initial form is displayed, the user can switch between the two forms by responding to the prompt with either CONDENSED or EXPANDED. The user can only switch to another form if there was a prompt string provided for that form. Responding with either CONDENSED or EXPANDED causes a reprompt to occur, even if the current display form was not switched. If a prompt routine is provided, the routine is called with the address of the prompt string descriptor in the first parameter, and the string descriptor address to receive the user's response in the second parameter. The routine returns a success status or RMS$_EOF. If an unsuccessful status other than RMS$_EOF is received, then UTIL$CQUAL_CONFIRM_ACT exits without processing any response in the response buffer (the second parameter that was passed to the prompt routine). UTIL$CQUAL_CONFIRM_ACT returns the status received from the user prompt routine. The prompt routine is responsible for end-of-file processing, and must return RMS$_EOF when appropriate. If an optional prompt routine is provided, it should be provided for all calls to UTIL$CQUAL_CONFIRM_ACT. Not doing so can cause unpredictable end-of-file processing. When the user is prompted, they may respond with the following: Table 4-3 Prompt Responses Positive Negative Stop Stop Switch Response Response Processing Prompting Prompts YES NO QUIT ALL CONDENSED TRUE FALSE Ctrl/Z EXPANDED 1 0 <Return> NOTE Entering ALL assumes that subsequent files are a positive response from the user, and no further prompting occurs. The routine UTIL$CQUAL_FILE_MATCH properly handles this response. Since UTIL$CQUAL_CONFIRM_ACT does not contain context from a previous call, callers of this routine should not call UTIL$CQUAL_CONFIRM_ACT if the user has previously responded ALL unless the application needs explicit confirmation on certain items. The user can use any combination of uppercase and lowercase letters for word responses. Word responses can be abbreviated to one or more letters (for example, T, TR, or TRU for TRUE), but these abbreviations must be unique. After a valid response is received from the user, the procedure returns the current_form parameter. The current_form parameter contains the last form presented to the user if it was specified and write access is permitted.
