**coef <matrix> <vec> [year]**- Convert the named flow matrix to a coefficient matrix by dividing each column of the matrix by the corresponding element of the named vector. If no year is named, the command works over the
*fdates*range. **flow <matrix> <vec> [year]**- Multiply each column of the matrix by the corresponding element of the named vector. If no year is named, the command works over the
*fdates*range. This command is the opposite of*coef*command. **getsum <matrix> <r|c> [<group>] <vector>**- Get the sum of the rows or columns of a given matrix for the range of periods specified by the
*fdates*. The first argument must be the matrix or vector for which we want to obtain the sums. The matrix is assumed to be stored in the default vam file unless a bank letter is provided. The second argument must be ‘r’ or ‘c’ (to obtain the sum by rows or by columns). If only a partial sum is desired, then the columns or rows are specified next. The last argument is the vector where the result is to be stored; this vector must be located in the default vam file. The sum is calculated and stored for all years, so that we cannot have mixed information in the target vector. **load <vector_name>**When

*G7*is working on a vector in a Vam file, it pulls the whole time series for the vector into a sort of vector workspace. Usually, this is done automatically simply by referring to the vector or one of its elements. The*load*command enables the user to do this loading explicitly. It is used principally in connection with the*index*command.For example:

load pce

**store**- Store the currently loaded vector back to the Vam file with the modifications that have been made. This
*store*is automatic when a new*load*or implicit load is encountered. When a*quit*command is given with an unstored, loaded vector, the program will store the vector automatically.
