| Syntax: | ASC(string-argument) |
| Discussion: |
The ASC function returns the decimal value of the first byte of
the string-argument using the 8-bit ASCII code.
The string-argument may be a string constant, a single-element string variable, a string array element, a string expression, or a string function. Note: If the string-argument contains more than one character, only the first byte of the string-argument is evaluated for conversion. The resultant value for any non-null string is always a numeric value from 0 through 255. The value that results for any null string is always -1. The intermediate result of the ASC function is stored in an accumulator with a precision of 16.0. If this intermediate result is then moved into a receiving numeric variable, its precision is adjusted to the defined precision of that variable. |
| Example: |
VALUE = ASC("SIGNATURE")
In this example, the first byte of the string "SIGNATURE" (i.e.,
the letter "S") is converted to its decimal ASCII equivalent,
namely 83. This value is stored in the variable VALUE.
