Mine was COBOL on an IBM system 3 model 360 mini computer in vocational technical school back in '81 when I was 17, using 80-column punch cards. The following year it was RPGII using 96-column punch cards on the same type of computer and card reader.

For work: SAS (San Antonio Shoes) - most comfortable shoes I have ever, ever worn. Otherwise: New Balance - because they come in wide widths (I could have been a hobbit in a former life) At home: barefoot (hobbit reference again?)
