array invalid when try to assign krc2

rvsh · August 12, 2020 at 4:04 PM

Hi,

I would like to assign an array (string) to another array but I got error information that " right side: array invalid"

I tried many combinations and I can't find the right syntax.

Could you help?

Here is the sample code:

Code

DEF MSG(TOSHOW[]:IN)
  INT ANSWER
  INT OFSET
  DECL STATE_T STATE
  DECL MSG_T EMPTY_MSG
  CHAR TOSHOW[]

  EMPTY_MSG={MSG_T: VALID FALSE, RELEASE FALSE, TYP #NOTIFY, MODUL[] " ", KEY[] " ", PARAM_TYP #VALUE, PARAM[] " ", DLG_FORMAT[] " ", ANSWER 0}

  $MSG_T=EMPTY_MSG
  $MSG_T.MODUL[]=" "
>>>  $MSG_T.KEY[] = TOSHOW[] ; HERE IS THE ERROR (I CANT ASSIGN TOSHOW[] TO KEY[]) <<<
  $MSG_T.PARAM[]="PARAM"
  $MSG_T.PARAM_TYP=#VALUE
  $MSG_T.TYP=#NOTIFY
  $MSG_T.VALID=TRUE
END

well... you should get error 2224 in line 8, even before you get to line 12.

you are trying to dump values of all structure elements of several different structures into one...

and of course most of them don't exist in this variable

If I just change line 12 to

$MSG_T.KEY[]="my message"

It works ok.

But I want to add it from array/variable.

Could you help?

Use a loop:

for ii=1 to strlen(toshow[])

$MSG_T.KEY[ii] = toshow[ii]

endfor

or use strcopy()

yes but note that loop would not erase characters beyond strlen(toshow[]) so if using loop, next character should be zero (unless that is beyond declared string end)

StrLen not declared as function

Any Ideas why?

"Name not declared as function"

1. post your KSS version

2. post your code... how are you trying to use it exactly?

rvsh · August 17, 2020 at 11:57 PM

1. KSS4.1.7 SP08

Code

DEF MSG(TOSHOW[]:IN)
  INT ANSWER
  INT OFSET
  INT II
  DECL STATE_T STATE
  DECL MSG_T EMPTY_MSG
  CHAR TOSHOW[]

  EMPTY_MSG={MSG_T: VALID FALSE, RELEASE FALSE, TYP #NOTIFY, MODUL[] " ", KEY[] " ", PARAM_TYP #VALUE, PARAM[] " ", DLG_FORMAT[] " ", ANSWER 0}

  $MSG_T=EMPTY_MSG
  $MSG_T.MODUL[]=" "
  FOR II=1 TO STRLEN(TOSHOW[])
  $MSG_T.KEY[II] = TOSHOW[II]
  ENDFOR
  $MSG_T.PARAM[]="PARAM"
  $MSG_T.PARAM_TYP=#VALUE
  $MSG_T.TYP=#NOTIFY
  $MSG_T.VALID=TRUE
END

If I do for example "for II=1 to 4" then it works fine if toshow length is 4 or more.

I use it just like this

MSG("example text to show")
