CHANGE DO - CONTINUE TO DO - ENDDO

Syntax:

[DO NOT] CHANGE DO [-] CONTINUE TO DO [-] ENDDO

Function:

Systematically changes labelled CONTINUE statements which terminate DO loops to labelled ENDDO statements.

If the label of the CONTINUE statement is also referenced by a GOTO statement (or by a destination label in an I/O statement or sub-program alternate return) a new label is created for the GOTO.

If the label is referenced by two or more DO loops, new labels are created and separate ENDDO statements are written.

The labels may be removed from the ENDDO statements by the command: REMOVE LABELS FROM ENDDO STATEMENTS.

The two operations, replacing DO - CONTINUE and removal of the labels, have been implemented independently because some users prefer to leave labels on long DO - ENDDO constructs so that the start and end of the construct may be identified unambiguously.

Where to Use this Command

Operating system command line	Yes
Configuration file, config.fsp	Yes
Specification (fsp) files, *.fsp	Yes
Interactively, to FPT> prompt	Yes
Interactive command files	Yes
Embedded in the Fortran code	Yes

Default

DO - CONTINUE constructs are not changed by default (Note that defaults may be modified in the configuration file).

Examples:

The command-line command:

$ fpt heli "%change do continue to do enddo"

results in modification of:

DO 2120 I=1,10 COL(I)=0.0 DO 2120 J=1,5 COL(I)=COL(I)+SS(I,J) 2120 CONTINUE

to:

DO 1240 I=1,10 COL(I)=0.0 DO 1230 J=1,5 COL(I)=COL(I)+SS(I,J) 1230 ENDDO 1240 ENDDO
