Hi all
can anybody help me with an example on how to find the occurence of a string in another string.whether true or false type.

if i have a message " hello neelam29 do the coding ". is it possibel that the function finds whether 29 is present in this string and returns only TRUE OR FALSE not the number 29.

m using mplab as the compiler and pic16f877 as the controller with visiontek GSM modem.

thanks all
