Summary -

In this topic, we described about the below sections -

The string operator put together two or more character-like operands and forms a string expression. The string expression result is a character string.

String expressions can occur on the right side of an assignment with the assignment operator =. The string expressions operands must have character-like data types.

Syntax -

| character-string1 | & | character-string2| & | character-string3|… .

{ operand1 && operand2 [ &&  operand3 ... ] }… .

  • A character string is enclosed in two "|" characters.
  • A character string starts with "|" and closed with "|" on the same line of the source code.
  • When character strings are combining with &, 255-character restriction applies on it.
  • When string expressions are combining with &&, trailing blanks are ignored.
Note! String expressions and arithmetic expressions can not be mixed.

Example -

Below example shows how the string operations coded in the program.

Explaining Example -

In the above example, each and every statement is preceeded with a comment to explain about the statement. Go through them to get clear understanding of example code.

W_R = | HELLO | & | WORLD..! |, concatenation (&) of srings enclosed in two "|" and retains all spaces after concatenation. Similarly, all the concatenations retains all spaces from inputs after concatenation execept below.

W_R = ' HELLO ' && ' WORLD..! ', concatenates the strings but retains only one space between the strings and retains strings in all other places.
