Hello there, I try to tokenize a string. "Normally" (which means on my normal PC) I use the strtok() function to tokenize my string. But Keil uV does not support this function in there stdlib. Any suggestions how to tokenize a string into its values? The string is of this format: "123 456 789 012" I want to get four integers with the values "123", "456", "789" and "012". If a single space as delimiter causes problems, it will be now problem to replace it to a tab "\t" or to any other delimiter. Thanks for any help and/or hints to solve my problem... Alexander
