Checking a string parameter
With the INSTR function you can check whether a string parameter is
contained in another string parameter.
Select Q parameter functions.
Select the FORMULA function.
Enter the number of the Q parameter in which the
TNC is to save the place at which the search text
begins. Confirm with the ENT key.
Shift the soft-key row.
Select the function for checking a string parameter
Enter the number of the QS parameter in which the
text to be searched for is saved. Confirm with the
ENT key.
Enter the number of the QS parameter to be
searched, and confirm with the ENT key.
Enter the number of the place starting from which the
TNC is to search the substring, and confirm with the
ENT key.
Close the parenthetical expression with the ENT key
and confirm your entry with the END key.
Example: Search through QS10 for the text saved in parameter
QS13. Begin the search at the third place.
If the TNC does not find the substring, it saves the value 0
in the result parameter.
If the substring is found in more than one place, the TNC
returns the first place at which it finds the substring.
