Hi-
I am just learning... I am trying to write a program using string commands. Specifically trying to identify number of words and spaces in a sentence

Alright.
We can't help you, unless you tell us what problem you're having. Do you want a list of common string functions? If so, here: STR$(numeric-variable) - Takes a numeric variable, and returns a string with those numbers in it. For instance, if numeric-variable had 123 in it, the string would be "123". RIGHT$(string-expression,numeric-expression) - Takes the string in string-expression, and returns the right most numeric-expression number of letters. LEFT$(string-expression,numeric-expression) - Same as above, except returns the left most numeric-expression number of letters. The following is taken from QBasic help, on the MID$ function: Quote:MID$(stringvariable$,start%[,length%])=stringexpression$Hope that helps.
f only life let you press CTRL-Z.

instr and especially mid$ might be useful to you. see the qb help (or the link) to find out what they do
to find the location of every occurance of a space, find instr, and set instr's pointer to the last value it gives until it finds nothing. then record these, and use mid$ to separate the words.

To find out how many spaces or words there are in a string, you have to compare each character in the string with the space (" ") string.
This is really easy... Read up on the MID$ command and LEN command, and use a FOR...NEXT loop to count the spaces. One point: It don't work for those strings with double spaces. If you can do the first part, try working on this slight problem. I, for one, am interested in a program like this, cos its the type of program that you think "I could probably make it but I can't be bothered" :wink:

look at the top where a link says "qboho".
either way, it's qbasicnews.com/qboho . but all it is is qb's help converted to html. you can get the same thing pressing 'f1' inside qb.

But you were on the site!!! Check the top of the page, below the QBasicnews title on the right. It will say Back to QBasicNews.com and below that QBOHO. Or you can click here.
