|
|
I have come across a weird change. One of my programs contains this line:
Code: | I=WINIO@('%nlTraverse Root name (2 letters e.g. AA)'//
& '%fn[Arial]%ts%`bg[white]%3^rs%sf&',
& 1.25D0, A0, iRoot) |
A0 is CHARACTER*(2)
Using a straight version of FTN95 6.10 with no changes to salflibc.dll, I can enter 2 characters into the box before I get a 'bing' sound. Using the beta salflibc.dll, I can only enter 1 character before I get the 'bing'. This is not anything to do with the callback function iRoot, although iRoot does contain BEEP@, because I have tried it with WRITE statements before and after the BEEP@s, and they are not accessed. Moreover, if I make the character variable A0 into CHARACTER*(3), I can get the desired 2 character input, and only get 'bing' when I try a 3rd character in input.
I have tried this with my 6.10 (with beta salflibc.dll) and also 6.35 pe version (again with beta salflibc.dll). I also tried increasing the %3^rs to %5^rs, to no effect. I wonder if it is one of those dreaded "reversions"?
A tiny test code that shows it is:
Code: | WINAPP
PROGRAM SURVEYOR
CHARACTER*(2) A2 ! allows 1 character only
CHARACTER*(3) A3 ! allows 2 characters
INTEGER, EXTERNAL:: iRoot
INCLUDE <WINDOWS.INS>
A2=' '
A3=' '
I=WINIO@('%nlTraverse Root name (1 letter only e.g. A) '//
& '%fn[Arial]%ts%`bg[white]%3^rs%sf&',
& 1.25D0, A2, iRoot)
I=WINIO@('%2nlTraverse Root name (2 letters e.g. AA) '//
& '%fn[Arial]%ts%`bg[white]%3^rs%sf&',
& 1.25D0, A3, iRoot)
I=WINIO@('%sf')
END
INTEGER FUNCTION iRoot()
iRoot = 1
END |
The program gets an outing once a year for a week, and this is the week! (My colleague who is using it, knows that I am an inveterate tinkerer, and thinks that I have changed something ...)

PS - ignore the superfluous %sf. |

I think that is change results from a fix in salflibc.dll. This change limits the size of the edit buffer for %rs to the size of the related character variable. Otherwise ClearWin+ will copy back more characters than there is space for.
It is possible that I should have allowed one more character but this may have something to do with a NULL terminator in C.
I will log this for investigation. |

I am sure that it is something of the kind. I was already allowing for letters bigger than an average by specifying %3rs when I only wanted 2, and it is definitely a change. You wouldn't notice it so easily for a long string.

I have fixed this for the next beta release (coming shortly I hope). |
