# (indirection) CATALOG # varNameString Refers to the variable whose name is varNameString. This lets you create and modify variables from a program using strings. Program segment: © :Request "Enter Your Name",str1 :NewFold #str1 © © :For i,1,5,1 : ClrGraph : Graph iù x : StoPic #("pic" & string(i)) :EndFor © G (gradian) MATH/Angle menu expression1G ¡ ⇒ expression list1G ¡ ⇒ list matrix1G ¡ ⇒ matrix This function gives you a way to use a gradian angle while in the Degree or Radian modes. In Radian angle mode, multiplies expression by p/200. In Degree angle mode, multiplies expression 1 by g/100. In Gradian mode, returns expression1 unchanged. In Degree, Gradian or Radian mode: cos(50G) ¸ ‡2 2 cos({0,100G,200G}) ¸ {1,0.-1} ô (radian) MATH/Angle menu expression1ô ⇒ expression list1ô ⇒ list matrix1ô ⇒ matrix In Degree angle mode, multiplies expression1 by 180/p. In Radian angle mode, returns expression1 unchanged. In Gradian mode, multiplies expression1 by 200/p. This function gives you a way to use a radian angle while in Degree and Gradian mode. Hint: Use ô if you want to force radians in a function or program definition regardless of the mode that prevails when the function or program is used.
