FORMAT: ATN(<number>)

**Action:** This mathematical function returns the arctangent of the
number. The result is the angle (in radians) whose tangent is the number
given. The result is always in the range -π/2 to +π/2.

10 PRINT ATN(0) 20 X = ATN(J)*180/π : REM CONVERT TO DEGREES

FORMAT: CHR$ (<number>)

**Action:** This function converts a Commodore ASCII code to its character
equivalent. See Appendix C for a list of characters and their codes. The
number must have a value between 0 and 255, or an **?ILLEGAL QUANTITY** error
message results.

10 PRINT CHR$(65) : REM 65 = UPPER CASE A 20 A$=CHR$(13) : REM 13 = RETURN KEY 50 A=ASC(A$) : A$ = CHR$(A) : REM CONVERTS TO C64 ASCII CODE AND BACK
