GSC. Command
Get Substring/Delimiter Count
Intention
Returns the number of occurences of a given substring or delimiter within a main-string.
There are several modes of operation. General usage is easy:
GSC.$$MAI|$$SUB
DBP.Result is: $$000
Which will get the number of delimiters. You can also count the number of delimited elements by adding the flag "d".
GSC.$$MAI|$$SUB||d
DBP.Result is: $$000
If you add the flag "a" the nany of the elemnts in P2 will be treated as delimiter. Like this:
$$MAI=Ralf,Peter;Mark.Paul
$$SUB=;,.
GSC.$$MAI|$$SUB||da
DBP.Result is: $$000
Syntax
GSC.P1|P2[|P3][|P4]
Parameter Explanation
P1 - Main-String
P2 - Sub-String/Delimiter
P3 - (optional) Variable for the result of the operation.
If omitted, TOS is used.
P4 - (optional) Flags. Can be any or all of the following letters:
"a" - then ANY of the characters in P2 is been treated
as delimiter/string to count.
"d" - then elements are counted, rather then delimiters,
result will be higher.
"e" - equal-case-mode is switched on
