G0176 : Argument out of range

An 'argument' is the input to a function. 'Out of range' means that the input supplied is not in the range of valid inputs. For example, the GAUSS function 'strindx', finds the location of a sub-string inside of another string:

sub_string = "abc";
full_string = "123abc456";

//First character of 'full_string' to check
strt = 1;

//Find index of 'abc' inside of '123abc456'
idx = strindx(full_string, sub_string, strt);

The above code will set 'idx' equal to 4, telling us that 'abc' can be found by looking at the 4th character of '123abc456'. The valid range of 'strt', the first character to check is from 1 to the number of characters in the string. If we change the value of 'strt' from 1 to 0 (which is not in the valid range for that input), like this:

sub_string = "abc";
full_string = "123abc456";

//First character of 'full_string' to check
//Zero is out of range for this input
strt = 0;

//Find index of 'abc' inside of '123abc456'
idx = strindx(full_string, sub_string, strt);

we will get the GAUSS error 'G0176: Argument out of range'.
