... ( ... occ = occ ... ) ...
In string functions in which searches are carried out, the
occ parameter specifies the number of matches that are to be searched for in the search range.
occ is a
numerical expression position.
occ is positive, occurrences are counted from the left; if
is negative, occurrences are counted from the right. The values 1 and 2 therefore mean the first and second occurrence, for example. Similarly, the values -1 and -2 mean the last and second last occurrence.
The default value for
occ is 1. If 0 is specified as the value in a function
other than the
replace function, an exception of class CX_SY_STRG_PAR_VAL is triggered.
