Interrupt code conversion for efficient computer program recovery. In response to an error being detected while processing instructions of a computer program running on a computer system, the OS receives a first program interrupt code (PIC) and interrupts the computer program. Control of the computer program is passed to a program interrupt handler and the program interrupt handler inspects the first PIC issued as a result of detecting the error. The first PIC is converted to a second PIC wherein the second PIC is associated with another error predicted when subsequent running of the computer program occurs. The second PIC is presented to a recovery routine associated with the computer program and, in response to the detected error, running of the computer program is customized based on the second PIC rather than the first PIC.
