What happened?Ī zero appeared on the screen, which was not what I had expected Why is their application being largely ignored?'īefore going further, I would like to share my first experience as aīASIC programmer, on a Commodore-64. 'Those arithmetic values are immensely useful Numbers - specifically, 0 and -1 in the case ofīASIC. The CPU's logic gates process such expressions using P > Q, is internally evaluated for its relative

I have found no other web page that addresses this issue, per se. Logical expressions, except in regards to the usage of the bitwise Those manuals make no further reference to the numeric value of Relationships and return a true or false value to be used in a decision'. You can use logical operators to connect two or more 'A logical operation uses Boolean mathematics to defineĪ logical connection between the results (-1 or 0) of relational The GW-BASIC 3.20, Epson, 1986, is nearly as terse: Return a result of -1 (true) or 0 (false)'. 'When two values are compared, the relational operators The GW-BASIC Reference, McGraw-Hill, 1990, features a similar This result can then be used to make a decision

The result of the comparison is either true (-1) orįalse (0). 'Relational operators let you compare two values. The GW-BASIC User's Guide and Reference, Microsoft, 1989,Ĭontains a small section explaining the function of relational operators. These methods are particularly useful in streamlining macrosįor spreadsheets, any version of BASIC, and even some word-processors. Of GW-BASIC, I have upgraded some of the code to look like output from modernĬompilers.
