 |
|
I didn't have this problem in 2009 but now -
CHARACTER*8 STRINGS(3)
STRINGS=(/'Longer ','Short ','Longest '/)
STRINGS=TRIM(STRINGS)
PRINT '(/(A8))',STRINGS
END
doesn't work properly. OK if longest first, otherwise not.
Truncation is determined by the first string. |

This should fail to compile because TRIM is not "elemental".
You could use...
| Code: | CHARACTER*8 STRINGS(3)
STRINGS=(/'Longer ','Short ','Longest '/)
do i=1,3
STRINGS(i)=TRIM(STRINGS(i))
enddo
PRINT '(/(A8))',STRINGS
END |

PRINT *,TRIM(STRINGS) fails to compile
but STRINGS=TRIM(STRINGS) compiles OK |

It may compile, but the assignment, as well as the assignment STRINGS(i)=TRIM(STRINGS(i)) in a DO loop, does nothing useful. The expression on the right of the assignment is a trimmed string. However, when a string expression is assigned to a variable, the expression is truncated or padded up with blanks to match the length of the CHARACTER variable.
Try | Code: | | PRINT '(/(1h|,A,1h|))',(TRIM(STRINGS(i)),i=1,3) |

Good point.
The original code does indeed compile under FTN95 but this reflects a bug in FTN95. It should produce a compilation error report. |

| I have fixed this bug for the next release (after 6.35). |
