White space
Description
Blanks, tabs, form feeds, and comments are forms of white
space. The compiler treats white space as a delimiter and does not
consider the number of white space characters.
Usage
White space in string literals
The number of white space characters is preserved when they
are part of a string literal (enclosed in single or double quotation
marks).
Dashes in identifiers
Unless you have prohibited the use of dashes in identifiers
(see “Identifier names “),
you must surround a dash used as a minus sign with spaces. Otherwise,
PowerBuilder considers the dash as part of a variable name:
|
1 |
Order - Balance // Subtracts Balance from Order |
|
1 |
Order-Balance // A variable named Order-Balance |
Examples
Example 1
Here the spaces and the comment are white space, so the compiler ignores
them:
|
1 |
A + B /*Adjustment factor */+C |
Example 2
Here the spaces are within a string literal, so the compiler
does not ignore them:
|
1 |
"The value of A + B is:" |
