96AF Get Integer result of expression

Submitted by Steve Fewell

Description:

[If called from &96AC, this routine will check for a comma ',' (issuing a "Missing ," error if one is not found), before
continuing with the rest of this routine].

This routine calls the Expression Handler routine (&9D3B)
to obtain the value of the expression on the command line.
If the value is a String, then a Type Mismatch error will be generated.
If this value is a Float then it will be converted to an Integer.
Exit with the Integer value.
