# ASC Function

#### Purpose:

To return a numeric value that is the ASCII code for the first character of the string x$.

#### Syntax:

    ASC(x$)

#### Comments:

If x$ is null, an "Illegal Function Call" error is returned.

If x$ begins with an uppercase letter, the value returned will be within the range of 65 to 90.

If x$ begins with a lowercase letter, the range is 97 to 122.

Numbers 0 to 9 return 48 to 57, sequentially.

See the CHR$ function for ASCII-to-string conversion.

See Appendix C in the GW-BASIC User's Guide for ASCII codes.

#### Examples:

    10 X$="TEN"
    20 PRINT ASC(X$)
    RUN
     84

84 is the ASCII code for the letter T.
