Checking a string parameter
The
INSTR
function checks 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 for the
result and confirm with the
ent
key. The TNC
saves in the parameter the position at which the
sought-after text begins.
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
Remember that the first character of a text sequence
starts internally with the zeroth place.
If the TNC cannot find the required substring, it will
save the total length of the string to be searched
(counting starts at 1) 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.
Example: Search through QS10 for the text saved in parameter
QS13. Begin the search at the third place.
37 Q50 = INSTR ( SRC_QS10 SEA_QS13 BEG2 )
