String Functions
Table 8-2 on page 8-3 shows the string functions supported by the native CRE library.
The native CRE does not provide pTAL prototypes for these functions. It provides only
the function names. Note that the function names are case-sensitive. You can use the
function prototypes in the C header files as examples when writing your own pTAL
prototypes for these functions.
