alphaNumCmp

alphaNumCmp( 
S_arg1 
S_arg2 
[ g_arg3 ] 
) 
=> 1 / 0 / -1

Description

Compares two string or symbol names alphanumerically or numerically.

If the third optional argument is non-nil and the first two arguments are strings holding purely numeric values, then a numeric comparison is performed on the numeric representation of the strings.

Arguments

S_arg1	First string or symbol to compare.
S_arg2	String or symbol to compare against S_arg1.
g_arg3	If non-nil, can cause a numeric comparison of S_arg1 and S_arg2 depending whether those arguments are strings holding purely numeric values.

Value Returned

1	If S_arg1 is alphanumerically greater than S_arg2
0	If S_arg1 is alphanumerically identical to S_arg2.
-1	If S_arg2 is alphanumerically greater than S_arg1.
