I have FORTRAN namelist files, that have the form like






In these files there are no blank lines as automatically put in above,

The goal is to read such files into Maple and have the same varNames created in Maple to be names/symbols with the values shown in the FORTRAN file assigned to those Maple names. In other words, Maple should then have

varName1 := 0.600:

varName2 := 123:

varName3 := 345.0:

This would enable the Maple to use these variables in the usual way to make calculations, etc.

I know how to read the FORTRAN files and get the varNames and values into two separate Maple tables, but I haven't found a way to then make the Maple assignments that are required. There must be a way to accomplish the goal.

Thank you for any suggestions.

Can I specify a unit for a symbol using the Units package, so that when I substitute a value for that symbol into an expression, the units for the value are already known?

I have used the components palette to build a user interface for a complex data analysis and display task. It involves multiple worksheets running in shared kernel mode. The main worksheet is organized as a 3x2 table, each cell of which uses components to display a set of some 25 related data parameters and controls. A second worksheet contains buttons and plot regions for graphing the columns of various data Matrices associated with the parameter sets. The parameters are stored in databases, and the Matrix data have been generated from the parameter sets as input by a stand-alone Fortran program. A third worksheet contains spreadsheets for examining the data in the Matrices. The various buttons on these Worksheets call the procedures in a library devoted to the interface, which procedures accomplish things like loading parameter or data files, clearing or updating the displayed parameter sets, executing data analyses, etc. Keeping so many components straight in my mind demanded that I adopt a uniform naming scheme, so the generic component names have all been replaced by my mnemonic ones which are derived from the underlying data content of each component. All this is pretty much nothing fancy, just as it MUST be, given what I'm trying to accomplish. Now I want to augment the user interface to include another set of parameters, controls and data Matrices all of which are disjoint from the existing ones.
