String with single backslash in SKILL

greatqs

Hi,

I had problem to create a string having only single backslash.  For example, I'd like to create a string "\123456\".

However, I tried below cases and they don't work. Also I don't understand why "printf" and "sprintf" behave differently on this. Anyone could help?

; Print "\123456\" on CIW but not I need

printf("\\123456\\")

; Get "\\123456\\" string but not I need (only single backslash)

sprintf(nil "\\123456\\")

; Get "\\123456\\" string but not I need (only single backslash)

strcat("\\" "123456" "\\")

  • All of these are actually creating the string "\123456\". If you use strlen() on the result of the sprint or the strcat, you'll see it returns 8. Similarly if you used any of the functions such as substring, you'd also find the second character is 1, and so on. 

    What  you're seeing is that when the return value from a function is displayed in the CIW, it shows strings in a form that can be re-entered. So that means it displays them with the appropriate escapes in place so that they can reconstruct the same string. When you use printf() however it doesn't do that (it also doesn't show the quotes around the string then either).

    So you need to enter \\ because you need to escape the backslash - but it actually only creates a single backslash.

    Regards,

    Andrew.

  • Andrew,

    Thank you so much! I understand it now.
