Depends on which language you're using. For Assembler, use the PACK didactics. For PL/one have a PIC declare of your CHAR field and assign the Moving picture to the DECIMAL Fixed field. due east.g. Code: DCL        CHAR_FIELD           CHAR(5); DCL        PIC_FIELD            PIC'(5)9' BASED(ADDR(CHAR_FIELD)); DCL        DEC_FIELD            DEC FIXED(five);    CHAR_FIELD = '12345'; DEC_FIELD   = PIC_FIELD; Regards, Garry

Both operands accept length fields Code:    PACK  DOUBLE,0(4,R8) . . . . . DOUBLE   DS   D volition pack a 4-grapheme field at R8 into the doubelword field named DOUBLE. This could also be coded as Lawmaking: PACK  0(8,DOUBLE),0(four,R8) Regards, Garry.

Really my requirement F_nomval is a graphic symbol filed of 16 bytes i have stored value four.000000 thru screen i declard F_nv_pack equally double give-and-take PACK F_nv_pack,f_nomval i checked the value of f_nv_pack by putting delibrate dump but iam getting value 0 in the F_nv_pack field could any 1 help me with query??? Many thank you in accelerate Kalpana

in that location is very niggling that we can exercise from here PACK/unpack are 2 of the most elementary and most dumb instructions ... review its clarification in the manual - they volition take anything as input an build the output according to the specifications - they will never plan cheque for information exception - they are GIGO ( garbage in garbage out ) instruction

Code: DCL        CHAR_FIELD           CHAR(5); DCL        PIC_FIELD            PIC'(five)9' BASED(ADDR(CHAR_FIELD)); DCL        DEC_FIELD            DEC FIXED(5);    CHAR_FIELD = '12345'; DEC_FIELD   = PIC_FIELD; What is the need of using based? can't we direct assign

Many thanks in advance Kalpana 4.000000 is not 16 bytes and it can not be packed since information technology is non numeric. In assembler the developer has to continue rail of where the decimal point is suppose to exist.

Hi Murugan, Quote: What is the demand of using based? This is for PL/1 only. "BASED" is used to overlay the CHAR field with a Motion-picture show field. Yous could also use Defined to accomplish the same result, but Define is, IMHO, less flexible. Quote: can't we directly assign No, You tin't assign a CHAR field direct into a DECIMAL FIXED field. Regards, Garry.
