The character constant edit descriptor causes a character string to be output to an external record. It takes one of the following forms:
'string'
"string"
The string is a character literal constant; no kind parameter can be specified. Its length is the number of characters between the delimiters; two consecutive delimiters are counted as one character.
To include an apostrophe in a character constant that is enclosed by apostrophes, place two consecutive apostrophes ('') in the format specification; for example:
50 FORMAT ('TODAY''S^DATE^IS:^',I2,'/',I2,'/',I2)Note that the symbol ^ represents a nonprinting blank character.
Similarly, to include a quotation mark in a character constant that is enclosed by quotation marks, place two consecutive quotation marks ("") in the format specification.
On input, the character constant edit descriptor transfers length of string characters to the edit descriptor.
Consider the following '(3I5)' format in the WRITE statement:
WRITE (10, '(3I5)') I1, I2, I3 This is equivalent to:
WRITE (10, 100) I1, I2, I3
100 FORMAT( 3I5)The following shows another example:
! These WRITE statements both output ABC'DEF
! (The leading blank is a carriage-control character).
WRITE (*, 970)
970 FORMAT (' ABC''DEF')
WRITE (*, '('' ABC''''DEF'')')
! The following WRITE also outputs ABC'DEF. No carriage-
! control character is necessary for list-directed I/O.
WRITE (*,*) 'ABC''DEF'
Alternatively, if the delimiter is quotation marks, the apostrophe in the character constant ABC'DEF requires no special treatment:
WRITE (*,*) "ABC'DEF"
