NAME
ask - ask parameter from terminal
SYNOPSIS
#include
char *ask (prompt, datatype, ans, anslen)
char *prompt;
int datatype;
char *ans;
int anslen;
DESCRIPTION
The prompt parameter is written to standard output, and one line
is read from standard input. If the response is valid for the
datatype specified, the response is written as a character string
into the location pointed to by the ans parameter. A pointer to
the response is also returned by ask.
If the response is longer than anslen-1 characters, or is not
valid for the data type specified, an error message is written to
standard output and the prompt is reissued. The error message
displays the original input and what data type it should be, for
example:
03/32/81 not a valid date
The valid datatypes are named in the include file and are:
BOOLEAN_TYPE MONEY_TYPE
CHAR_TYPE REAL_TYPE
DATE_TYPE STRING_TYPE
INT_TYPE TIME_TYPE
