_BCDTRIM - "trim" trailing blanks from a BCD string.

(GCOS-8 Only)


newlength = _bcdtrim(bcdptr,oldlength);


void *bcdptr;
indicates the BCD string to be trimmed. This must be a BCD pointer as created by "_bcdptr".
int oldlength;
is the current number of BCD characters in the string.
int newlength;
is the number of BCD characters in the string, omitting any trailing blanks.


"_bcdtrim" calculates the number of trailing blanks on a BCD string and returns the length of the string if trailing blanks were omitted. By specifying this new length for the string instead of the old one, you effectively "trim" the trailing blanks in any operations on the string.
