B4P Reference

Introduction

The data subtype quoted string is applied in following cases:

Text inside double quotation marks is written into B4P variables and used in any expressions.
Unless specified otherwise, almost all B4P functions which return values of type string are of subtype quoted strings.
The contents in quoted strings are always considered and interpreted as literally given:
- No symbols like '*' or '?' are treated as wildcard symbols for comparisons

With Text Inside Double Quotation Marks

       a[] = "Hello World";

       b[] = "Hello   World";

       c[] = "  Hello World  ";



       echo( 'a[] = "', a[], '"');

       echo( 'b[] = "', b[], '"');

       echo( 'c[] = "', c[], '"');

       echo( 'Subtype of a[] is ', subtype( a[] ) );

       echo( "Simple comparison returning 'false': ", Hello = "*llo" ); // quoted strings support no wildcards

Output:

a[] = "Hello World"
b[] = "Hello   World"
c[] = "  Hello World  "
Subtype of a[] is quoted string
Simple comparison returning 'false': false
