* * * * * * * * * * * * * * * * The first column is the average number of iterations the linear solvers attempted to obtain the specified linear equation convergence criteria (within a specified number of iterations). The second column gives the normalized residuals for the solutions to the linear equation. The last column can have one of four entries: * indicates that there was a numerical floating point exception and this resulted in the failure of the linear solvers. F indicates that the linear solvers did not reduce the residuals (i.e., the solution was diverging), but the linear solvers may carry on if the divergence is not catastrophic. ok indicates that the residuals were reduced, but that the degree of reduction did not meet the specified criteria. OK indicates that the specified convergence criteria for the reduction of residuals was achieved. CASE SENSITIVITY Everything in the file is sensitive to case. EFFECT OF SPACES Spaces appearing before or after a name are not considered to be part of the name. Single spaces appearing inside a name are significant. Multiple spaces and tabs appearing inside a name are treated as a single space. CCL NAMES DEFINITION In simple syntax, a CCL name must be at least one character. This first character must be alphabetic; there may be any number of subsequent characters and these can be alphabetic, numeric, space or tab. PARAMETER VALUES STRING The characters $ and # have a special meaning. A string beginning with $ is evaluated as a Power Syntax variable, even if it occurs within a simple syntax statement. The characters such as [, ],{ and } are special only if used in conjunction with $. Following a $, such characters terminate the preceding Perl variable name STRING LIST A list of string items separated by commas. e.g names = one, two, three, four INTEGER If a real is specified when an integer is needed, the real is rounded to the nearest integer. REAL a = 12.24 a = 1.224E01 a = 12.24 [m
