IBM Abbreviations
IPL - Initial Program Load
Starting or restarting the system. This acronym was pronounced eye-pee-ell and was used as a verb ("IPL the system") with past tense ("then we IPLed") and present tense ("while we were IPLing") and so forth - as well as a noun ("after the next IPL.")
APAR—Authorized Program Analysis Report
An APAR announced the entry of each new System/34 bug into the IBM process. If it was a genuine problem, the details would be sent for resolution to Rochester (for system problems) or Menlo Park / Rayners Lane (for application problems in MMAS, CMAS or DMAS). Eventually the APAR would be fixed by a corresponding PTF (see below).
PTF - Program Temporary Fix
IBM would distribute bug fixes on diskettes called PTF diskettes. By applying PTFs, the user could address software problems. When the next release was issued (S/34's last release was Release 9 in 1981) the old PTFs were incorporated into the release update diskettes the user received, and the old diskettes became useless. Since PTFs were only temporary in the sense that they were superseded by later releases of SSP, using the name "PTF" was considered odd.
