INSTR

Syntax: str1$ INSTR str2$
Location: QL ROM

This operator searches str2$ for str1$ and if found, it will return the position of the first character of str1$ in  str2$. The search is not normally case-sensitive. If str1$ cannot be found, the value 0 is returned.

Examples:
s$='Hello World':PRINT 'world' INSTR s$  will print 7.   

PRINT 'worlds' INSTR s$   will print 0.

NOTE:
If str1$ is a nul string, eg. str1$="", INSTR will always return the value 1.

SMS NOTE:
You can specify a case sensitive search using INSTR_CASE.

See INSTR_CASE.
INARRAY% and SEARCH can be used to compare entries within arrays.
