TRANS 2.21 -->, this was named TRANS.COM instead.<ref name="BYTE_2018_MASM"/><ref name="Paterson_2014_MSDOS125"/><ref name="SCP_1980_86-DOS"/><ref name="SCP_86-DOS"/><ref name="SCP_TRANS"/> Later in 1982, the translator was apparently also available from [[Microsoft]].<ref name="Taylor_1982_Translators"/><ref name="Hughes_1982_MS-DOS"/>
