"Original" Dartmouth BASIC did not allow statements after a codice_81, only a line number to branch to. SBASIC allowed any statement, so for instance codice_82. This basic expansion to the codice_9, pioneered in 1972 with BASIC-PLUS, was already widely supported by most variety of BASICs by this point, including microcomputer versions that were being released at this time. On top of this, SBASIC added block-oriented codice_84 by placing the codice_81 on a separate line and then ending the block with codice_86. On top of this, SBASIC added the codice_87 mechanism that survives to this day in VB.net.
