Charles Petzold: PC Tutor: Different BASICs. In: PC Magazine. Band5, Nr.10. Ziff Davis, 27. Mai 1986, S.267 (englisch, eingeschränkte Vorschau in der Google-Buchsuche): “Versions of MS-DOS for compatibles generally come with a version of BASIC called GWBASIC but may also include files named BASIC and BASICA, which are identical copies of the GWBASIC interpreter. (On the PC, BASIC and BASICA are different.)”
Stuard R. Greenberg: Languages – BASIC, Yes; Feeble, No: GW-BASIC and BASICA. In: PC Magazine. Band8, Nr.18. Ziff Davis, 31. Oktober 1989, S.202 (englisch, eingeschränkte Vorschau in der Google-Buchsuche): “While our tests show that BASICA is faster in screen I/O, improvements made by Microsoft to GW-BASIC gave it a faster execution speed than BASICA in non-screen operations. BSAVE and BLOAD test results showed GW-BASIC to be four times as fast because of file-buffering enhancements not present in BASICA. Since the differences between the two are mainly in operating speed, both programs will hereafter be referred to as GW-BASIC.”
