String comparison function in LR

Hi,

Thanks in advance,

Can any one help on string comparison function otherthan strcmp to use in Load Runner scripting.

I need to compare a string with the value captured and saved in LR variable.

For Example :  result=strcmp((lr_eval_string("{c_planGroupVal}"),"DC")

Please suggest me with an alternate string comparison function which can be used in LR script.

Regards
