• *MWRITE allows matrices to be output to a file.

• *MWRITE,ParR,Fname,Ext,Dir,Label,n1,n2,n3

– Writes ParR to a file using format descriptors (Fortran or C based) specified on the subsequent line

– Output order controlled by Label option (JIK default) and n1, n2, n3 available to limit output

– No limit to output line length

– Format descriptor line limited to 80 characters

• Available with *MSG, *VWRITE , And *MWRITE commands

– %I for integer, %G for double precision, %C for alphanumeric data

– C descriptors assumed if first character of format line is not left paranthesis “(“

Example: *VWRITE,nmax,x1360 X Coordinate of node %I is %g

Output: X Coordinate of node 1360 is 0.234567
