How to Use Continuation Lines When Printing Literal Strings

MORE INFORMATION

Do one of the following to prevent extra spacing of a literal string continued on a continuation line:

• In fixed form source code, enclose the literal string in quotation marks, and use the concatenation operator "//" at the end of the line with any character other than a blank or zero at the begining of the next line.
• In free-form source code, use an "&" at the end of the literal string to be continued and another "&" at the beginning of the continued literal string on the next line.

The following sample code demonstrates the problem of incorrectly using a literal string on a continuation line.

Sample Code #1

C Compile options needed: none
C Fixed form source code

C This prints 'Hi + 64 blank spaces + world'.

      print *,  'Hi
     &           world'
      end
				

The following two code samples illustrate the correct way to print a literal string on a continuation line:

Sample Code #2

C Compile options needed: none
C Fixed form source code

$NOFREEFORM

C This prints 'Hi world'

      print *,  'Hi' // 
     & ' world'
      end
				

Sample Code #3

C Compile options needed: none
C Free form source code

$FREEFORM

! This prints 'Hi world'

      print *,  'Hi&
     & world'
      end
