VARIANT
Syntax:
!% VARIANT [:] [:] <symbol> [ , <symbol> ... ] !% VARIANT [:] [:] <string> [ , <string> ... ]
Function:
This command is written as a comment in the Fortran code. It specifies that the named sub-program argument is of variant data type. fpt uses this information in the argument consistency check (please see CHECK ARGUMENTS). The named objects are assumed to be variant in data size and data type, and these checks are suspended for them.
Names which contain exotic characters such as "%", ":" or "#" (which are all legal on some systems) must be written as quoted strings.
The % VARIANT command must be written in code within the scope of declaration of the variable. It is introduced by a comment delimiter in column 1 and the character % in column 2.
