Description
The CHRTRAN() function will search <expC1> or <memofield> and replace text within <expC1> or <memofield> with <expC3> wherever the occurrence of <expC2> is found. If <expC3> is not specified, instances of the text in <expC2> are removed. The optional <expN1> specifies the start position for the search in <expC1>. If this is not specified then the default is 1. The optional <expN2> specifies the number of occurrences of <expC2> to replace with <expC3>. If this is not specified, then all occurrences starting from <expN1> are replaced. This function can be used to remove blank spaces in character strings. The CHRTRAN() function returns a character expression that contains the result of the string translation.
The CHRTRAN() function is synonymous with the STRTRAN() function.
