The basic BASIC program invokes the BASIC and/or FlashBASIC compiler, which translates the specified source code into executable object code with case-sensitivity in effect. This causes the compiler to only accept uppercase keywords.
The blist command formats and outputs BASIC source code listings, according to the options chosen. It can also be used to format a BASIC source program and write it back to the file from which it came.
The blkio BASIC program displays or sets the I/O blocking factor, or number of frames read in one disk access during sequential file accesses. The setting is global for the whole system, and can be changed at any time.
The break-key command toggles the availability of the BREAK key, or displays its present status when issued without options. If the PIB number is specified, the BREAK key status displays or is modified for the PIB number requested.
