Event_Handler macro - Extract substring by byte (character) position
Format: %scutc(string,start-pos,lenght)
- start-pos: bytecount from start of string. negative: count from end of string. Count start from zero!
- length: number of bytes to extract. Zero=rest of string.
If the specified substring is (partly) outside the input string, the result is silently truncated, and a shorter, but valid string is returned.
Useful for parsing External_Data_Input input.
Example:
%scutc(%edi,4,3) returns 3 characters from the input string, starting from char 5
More Examples:
%scutc(0123456789,2,3) returns 234 %scutc(0123456789,2,0) returns 23456789 %scutc(0123456789,-4,3) returns 678 %scutc(0123456789,-2,3) returns 89 %scutc(0123456789,-11,3) returns 01 %scutc(0123456789,11,3) returns empty string
