Module 9070 Copy a number from a string
The TNC searches a selectable string memory (S0 to S15) for a numerical
value. When the numerical value is first found, the TNC copies it as a string
into another selectable string memory. The TNC does not check whether a
conflict arises between the source and target string. It may overwrite the
source string (even then, however, the function of the module is ensured). The
TNC recognizes unsigned and signed numbers, with and without decimal
places. Both the period and comma are permitted as decimal point. The TNC
returns the position (in characters) of the first character after the found
number in the string memory to be searched.
Call:
PS
K/B/W/D <Address of the string memory to be searched>
