You can use a character constant instead of an H edit descriptor. Both types of format specifier function identically.
In a character constant, the apostrophe character is written as two apostrophes ('').
The following example shows how to write the apostrophe character in a character constant:
50 FORMAT ('TODAY''S DATE IS: ',I2,'/',I2,'/',I2)
When you use a pair of apostrophes in this way, they count as a single character.
For details on the H edit descriptor, see Section 8.4.5.1.
