trimming spaces in a string

Is there a command, similar to ALLTRIM, that removes the blank spaces in a string.

hi , it that is java that you are progarmming in , then the commmad is .trim() , and it will trim the spaces from the end .... i dont thing that there is something like this C .
Sorry slash, thats not correct. The .trim() function will only trim the whitespaces to the right and left of the string.. not the middle. To make this really simple.. convert the string to a character array, loop through the array one space at a time and if the character isnt a white space, copy it to another character array of equal size, if it is a whitespace, increment past it... when you are done, convert the character array back into a string. There may be a function out there that will do that, but I have never used it(Assuming your using java).

ALLTRIM() only removes the spaces on the ends of a string. To remove spaces in the middle, you'll need to write your own.
This will work for the most part in java as well. I think the string implementation is slightly different, though and you can't assume that the string is terminated with a 0.

And if it is Java, then using a StringTokenizer and a StringBuffer will probably be better (faster) than .trim().

Whaaa.. How scary. FoxPro string functions are best if you treat them a little like C strings. Using silly commands like MEMOLINE or whatever will actually slow you down.
