Is there a way to parse a string/char within a macro?

Example:

char p1[0] = ‘FILERIGHT’

I need to grad the fifth character in the filed and place it into it’s own char variable.

Move “R” into → char p2[0]

Would these be like grabbing the array within the char?

Hi @outbound6 ,

To parse the string of p1 and grab “R” from the string please set up a p2 char array to hold the value. Then using the assigment operator we can access the value of “R” at p1[4] and place it within the zero index of 2.

The example below grabs the value of R from the p1 array and places it within LW 0.

Please let me know if you have any questions.

macro_command main()

char p1[20] = "FILERIGHT" 
char p2[1] = ""

p2[0] = p1[4] // the fifth character is stored here

// and now p2[0] holds the fifth character and places it within LW 0
SetData(p2[0], "Local HMI", LW, 0, 1)

end macro_command
