TWTD — Transfer while true, destructive
TWTU — Transfer while true, update
TWSD — Transfer words, destructive
TWSU — Transfer words, update
TWOD — Transfer words, overwrite destructive
TWOU — Transfer words, overwrite update
TRNS — Translate – transfer a source buffer into a destination converting characters as given in a translate table.
TLSD — Transfer while less, destructive
TLSU — Transfer while less, update
TGED — Transfer while greater or equal, destructive
TGEU — Transfer while greater or equal, update
TGTD — Transfer while greater, destructive
TGTU — Transfer while greater, update
TLED — Transfer while less or equal, destructive
TLEU — Transfer while less or equal, update

Famous quotes containing the word transfer:
“I have proceeded ... to prevent the lapse from ... the point of blending between wakefulness and sleep.... Not ... that I can render the point more than a point—but that I can startle myself ... into wakefulness—and thus transfer the point ... into the realm of Memory—convey its impressions,... to a situation where ... I can survey them with the eye of analysis.”
—Edgar Allan Poe (1809–1849)
