[RBASE-L] - Re: Removing multiple spaces from a string

Hi Jim,

That's neat - so you can effectively replace a multitude of differentnumbers of spaces with a repetitive number of equal ones with thatfunction - if I understand it correctly?

So for typists with errant fingers you could remove the double and triplespaces that some use for no obvious reason?

What I'm currently doing is examining all my SET VAR commands in my RMD/EEPfiles.However, for years, I have set out my files in what I think is an easy wayto see that each one is defined correctly:


SET VAR vShort                              TEXT = NULL
SET VAR vVeryLongNameForVar TEXT = NULL
SET VAR vInteger                    INTEGER = NULL

It's those spaces between the name and the type that regularly vary.

Regards,
Alastair.

Alastair,

My favorite command language REXX has a marvelous function:
SPACE(string,n,pad)
Formats the blank-delimited words in "string" with n "pad:
characters between each word.

for example SET VAR vTval = 'aa   bb  cc dd'
set var vcln = (SPACE(.vTval,1,' '))
show var vcln
'aa bb cc dd'

Thanks for your responses.

I prefer the while loop to my goto so that's an improvement -
thanks Ben & Larry.

I looked at the SSTRIP(I) functions when I was searching for a
function that I was sure must exist to do what I wanted. I
concluded that I could take out all the spaces but that
wouldn't leave me a way to use SSUB. Thanks Mike, if I'm
missing a way to do what I want with it please let me know.

I had already discovered the problem with SLOC and double
spaces after I posted originally and before Larry's comments.
I'd got around it by replacing all spaces with a | and then
getting rid of the double ones - much as suggested.

It seems obvious to ask why SLOC has a problem identifying two
spaces? Is it an R:Base problem or a Windows/general computing
one? IF it's an R:Base one does it need reporting or is RBTI
aware already?

Also, is there a need for a function that can take out the
words from a string regardless of the number of spaces between
them? A sort of "Super-SLOC" that, perhaps, works on any
number of spaces rather than the comma (or whatever the
delimit is set to)?

Regards,
Alastair.

  Subject: [RBASE-L] - Removing multiple spaces from a string

  I am trying to remove all double spaces in text in order to
replace the remaining single spaces with a comma so that I can
use SSUB on the converted string.

  The target string (vVarData) may have an unknown number of
spaces between the words. There's no pattern from one string
to another. In theory there's no limit to the length of any
space although, in practice, it's likely only to be a few
space "characters".

  I expected to be able to come up with something rather more
eloquent than this:

  SET VAR vVarData = (TRIM(.vVarData))
  LABEL lSpaces
    SET VAR vCount = 0
    SET VAR vCount = (SLOC(.vVarData, '  '))
    IF vCount <> 0 THEN
      SET VAR vVarData = (SRPL(.vVarData, '  ', ' ', 0))
      GOTO lSpaces
      ENDIF
  SET VAR vVarData = (SRPL(.vVarData, ' ', ',', 0))
  SET VAR vWord3 = (SSUB(.vVarData, 3))
  SET VAR vWord4 = (SSUB(.vVarData, 4))
  SET VAR vWord6 = (SSUB(.vVarData, 6))

  Am I missing a more obvious method to get the end result?

  Regards,

  Alastair
