-As part of initialisation process VBASIC installs itself in the RAM area, address of which is normally occupied by BASIC ROM code, and adds additional routines at the very top of memory available for BASIC programs. It also verifies the presence of an installed BeamRacer card and activates it if found. Thanks to that your programs do not need to perform any additional steps to check and activate BeamRacer. Last but not least it adds helper routines and modifies several system variables and vectors in order to provide correct information about available memory and enable seamless experience with all the standard behaviour for STOP, STOP/RESTORE etc. working as usual, while actively maintaining both the VBASIC extension and BeamRacer active.+As part of initialisation process VBASIC installs itself in the RAM area, address of which is normally occupied by BASIC ROM code, and adds additional routines at the very top of memory available for BASIC programs. It also verifies the presence of an installed BeamRacer card and activates it if found. Thanks to that your programs do not need to perform any additional steps to check and activate BeamRacer. Last but not least it adds helper routines and modifies several system variables and vectors. This allows to provide correct information about available memory and enables seamless BASIC programming experience. As a result all the standard behaviour for STOP, STOP/RESTORE etc. remains unchanged, while actively maintaining both the VBASIC extension and BeamRacer active at the same time.
