Summary
| Description |
English: This card was used to load software into a mainframe computer. Each byte (the letter 'A', for example) is entered by punching out a column of holes.
Contents appear to be a line from a Fortran program: 12 PIFRA=(A(JB,37)-A(JB,99))/A(JB,47) PUX 0430where 12 is a statement label and PUX 430, starting in column 73, would typically be a card sequence number. Per author "You may scoff at the low-tech but this data has survived longer than most CD-Rs will last - they rot in a decade or so..." |
