strsubk

Extract a substring of the source string.

strsubk runs both at init and performance time.

Syntax

Sdst strsubk Ssrc, kstart, kend

Performance

kstart -- start position in Ssrc, counting from 0. A negative value means the end of the string.

kend -- end position in Ssrc, counting from 0. A negative value means the end of the string. If kend is less than kstart, the output is reversed.
