How to compare strings?

use STRCOMP() or use loop to check the strings yourself (char by char)

No its available since quite some time:
BOOL StrComp (CHAR strComp1[470] :IN, CHAR strComp2[470] :IN, CASE_SENSE_T CaseSens :IN)

strComp1 string to compare with strComp2
strComp2 string to compare with strComp1
CaseSens case sensitive or not (#CASE_SENS, #NOT_CASE_SENS)
return value Returns TRUE if the strings are equal

The following simple test worked fine for me

bool result
...
result = StrComp ("ABC”, "ABC”, (#CASE_SENS)) 
result = StrComp ("ABC”, "abc”, (#NOT_CASE_SENS))
result = StrComp ("ABC”, "abc”, (#CASE_SENS))
result = StrComp ("ABC”, "acb”, (#NOT_CASE_SENS))

Did you assign your result to a boolean?

Hallo ,Ich Habe eine KRC1 V4.1.7 SP5, und versuche gerade Strings zu vergleichen.

Bin noch Anfänger habe die RS232 über com2 am laufen und möchte darüber strings vergleichen.

Fehlermeldung Name nicht als Funktion vereinbart kommt wenn ich das schreibe

IF StrComp (RX_Buffer[],RX_BUFFER_SOLL[],#CASE_SENS)==TRUE THEN

Was mus ich denn genau declarieren um die Funktion ans laufen zu bekommen?

Habe StrComp als BOOL schon versucht.

please use English in this forum.

that KSS is too old and does not have string functions, ON_ERROR_PROCEED, $ERR etc.

this means you need to use a workaround such as external function or using fixed length strings where you specify the max length to compare.

example comparing first 3 characters (match):

example comparing 5 characters (mismatch):

not sure how to check string length in so old KSS so your strings may need to be padded with spaces
