From the command window: Issue the whatis command from the command
line, specifying the name of the variable as its argument.
5.5.1 What Is Displayed
Prism -displays the information about the variable in the command window. If a
CM Fortran array is CM-resident, that information is included. For example:
whatin primes
(CM based) logical primes (1:999)
5.6 Modifying Data
You can use the assign command to assign new values to a variable or an array.
For example,
assign z - 0
assigns the value 0 to the variable x. You can put anything on the left-hand side
of the statement that can go on the left-hand side in the language you are using -
for example, a variable, a Fortran array section, or a C* left-indexed parallel
variable.
If the left-hand side is a CM Fortran array or array section, the right-hand side
must be a conformable expression. For example, if arrayl and array2 are conformable,
assign arrayl - array2 + 2
adds 2 to each element of array2 and assigns the result to arrayl.
Similarly, if the left-hand side is a C* parallel variable, the right-hand side must
be of the same shape. For example, if pI and p2 are parallel variables of the same
shape,
assign p - p2
assigns the value of each element of n2 to the corresvonding element of pD.
