nBytes is a value that may range from zero (0) to 32767. If the value specified is less than 512, it rounds up to 512. Block size should be a minimum of 512, otherwise it will be rounded to nearest value divisible by 512.

Description

This command can be used to override the block size preference set in the Preferences.xml file for the currently running session of MapInfo Pro. You can issue this statement from the MapBasic window in MapInfo Pro.

Executing the command will not update the Preferences.xml file. Thus, the block size preference set using this command will not be applicable for the next sessions of MapInfo Pro.
