That's because the first COBOL compiler was introduced in 1961. At that time there is no SMALL LETTER in the computer keyboard. |

maverick05,
Try coding a COBOL program in all lower-case. You wont find any error. Its not a Convention |

| Also, for a long time many printers only printed in upper-case characters. |

I accept with you superk.
ANSI-68 COBOL introduced a facility to type in Small Letters also.
But Small letters are not in COBOL character set yet now.
So if you type in small letter, it's treated as the equivalent capital letter ASCII code by the COBOL compiler. |

The real reason was that the printers and the other equipment of the time made so much noise that the developers had to SHOUT.  |
