Remove last n character from string

[KSforex]

Hi

for example we have different strings:

1- "abcd abcde efg"

2- "abcd 123 efg jkl"

3- "abcd 456 tuv 567"

....

..

.

I want to remove last 4 characters .

There is no useful function here https://docs.mql4.com/strings . and can't use "StringReplace" because the last 4 character  are not fixed. how should I do this?

Thanks for help

 string p = "0123456789";
 string q = StringSubstr(p,0,StringLen(p)-4);
