If an accuracy is required, then we use the variable LBL: 80-87, 91-87, 99 (PICF) DSC: Pick an MVAR function and variable IN: X: integer FAQ: If X=0, then EqD is set to 1. Upper limit of second or dependent variableĪ step size for a second or dependent variable

Lower limit of second or dependent variable If a second variable is used, then similar variables are used however, we have no precedent for what to name them. Variables based upon names used by built in tools: Values we need to know lower and upper ranges over which to sum, and a step size by which to increment the variable. The collected information is housed in three globalĭepending on what we are doing with the MVAR program, we may need to know something about the independent variable too. All the top level programs use PICF to collect information about the MVAR program to be used.
