STRUCT(1) STRUCT(1) NAME struct - structure Fortran programs SYNOPSIS struct [ option ] ... file DESCRIPTION Struct translates the Fortran program specified by file (standard input default) into a Ratfor program. Wherever possible, Ratfor control constructs replace the original Fortran. Statement numbers appear only where still neces- sary. Cosmetic changes are made, including changing Holler- ith strings into quoted strings and relational operators into symbols (.e.g. `.GT.' into `>'). The output is appropriately indented. The following options may occur in any order. -s Input is accepted in standard format, i.e. comments are specified by a c, C, or * in column 1, and con- tinuation lines are specified by a nonzero, nonblank character in column 6. Normally, a statement whose first nonblank character is not alphanumeric is treated as a continuation. -i Do not turn computed goto statements into switches. (Ratfor does not turn switches back into computed goto statements.) -a Turn sequences of else ifs into a non-Ratfor switch of the form switch { case pred1: code case pred2: code case pred3: code default: code } The case predicates are tested in order; the code appropriate to only one case is executed. This gen- eralized form of switch statement does not occur in Ratfor. -b Generate goto's instead of multilevel break statements. -n Generate goto's instead of multilevel next statements. Will not generate Ratfor FOR statements.
