Create a SCL variable, of the nominated type (Logical, L4; Integer, I4; Real, R4; double precision, R8; or string, Cnnn [nnn is the length in characters of the string variable]). The variable may optionally be a one-dimensional array, with length as indicated by a bracketed length after the variable name.
Examples:
>> declare<CR>
Variable name? x<CR>
Type? (Cnnn/L4/I4/R4/R8) r4<CR>
>> declare y(8) r8
