VDU 5

Post by Ivan »

"VDU 5 causes text to be written at the graphics cursor position."

Is there a VDU 5 "OFF" switch, so I can use PRINT TAB again?
BBC Model B - 1984-1989. 6502 assembler, Unicomal 1988-1994, Some C and C++, Pascal 1990-1994. Bought a copy of BBC-BASIC 2007, but started to program at a daily basis 2019. C++ in 2021.

Other VDU commands which operate in pairs are VDU 2 & 3 (enable and disable printer), VDU 6 & 21 (enable and disable screen output) and VDU 14 & 15 (enable and disable 'paged' mode).
