The NX Nastran DMAP Language
Parameters Scalar quantities used to control the flow of
DMAP execution and to communicate options
and/or values to modules or functions.
Data Blocks Tables or matrices represented by a symbolic
name.
Instructions Statements or modules that process parameters
and/or data blocks as input and/or output.
• The DMAP language uses free-field input format and is case insensitive.
• A physical entry consists of information in columns 1 through 72. Columns
73 through 80 can be used for comments, but these columns do not appear in
the printed listing and are not stored on the database.
• For the specification of modules or statements, a parent entry continues to a
subsequent entry if it terminates in a comma [ , ] or a slash [ / ], or if it is
missing a right parenthesis [ ) ].
• The dollar sign [ $ ] ends any DMAP instruction and causes all subsequent
data to be treated as commentary. The recommended convention is to
terminate all DMAP instructions with a dollar sign.
• DMAP symbolic names are used to identify variable parameters, data
blocks, DBVIEW view-names, subDMAPs, or LABEL statements. A
symbolic name is composed of alphanumeric characters 1 to 8 characters in
length. The following characters are allowed: A through Z, and 0 through 9.
The first character must be a character from A through Z.
