MOVCHRDEC MOVE CHARACTER TO DECIMAL TAACLPJ
The Move Character to Decimal command allows for the situation where
a packed decimal value (e.g. X'010F') is in a CL character variable
and you want to treat it as a decimal value. For the inverse
function, see MOVDECCHR.
In most cases there is no need for MOVCHRDEC as you should
consistently specify parameter definitions to avoid this type of
However, there are cases where the MOVCHRDEC command is needed. For
example, when dealing with a command list of sub-lists where one or
more of the elements is numeric, extracting from the value passed by
command definition can only be done to a character field. You need
the MOVCHRDEC command to treat the element properly.
For example, assume you have a command which uses a list of sub-lists
where each sub list allows the entry of "Code ID" and "Quantity".
The command definition would be coded as follows:
PARM KWD(LIST) TYPE(LIST1) MIN(1) MAX(50) +
PROMPT('List of entries:')
LIST1: ELEM TYPE(*CHAR) LEN(5) +
ELEM TYPE(*DEC) LEN(3 0) +
The length of the sub-list passed from command definition will be 7.
The first 5 are the Code ID and the next two are a packed value for
Quantity. You must use the substring capability to extract the
Quantity value and therefore can only move it to a character
variable. To work with the data, you want it in a decimal variable.
The MOVCHRDEC command requires the character field to be in a LEN(8)
variable. So you must normally move the value first. The typical
commands would then be:
CHGVAR &WORK2 %SST(&SUBLIST 6 2) /* Extract from sub list */
CHGVAR &WORK8 &WORK2 /* Move to 8 byte var */
MOVCHRDEC DECOUT(&DEC) CHRINP(&CHAR) /* Move to decimal var */
The returned decimal value must be coded as LEN(15 0). The CHRINP
must be coded as LEN(8).
Note that you left adjust the value in the CHRINP variable.
The CHGVAR command can be used to convert data from character to
decimal. For example, if you have a character value of 123
(X'F1F2F3') using CHGVAR to a DEC(5 0) variable will convert the data
Unlike the CHGVAR command, MOVCHRDEC does not convert the data, but
rather moves the bytes to a decimal variable. The same bytes will
appear in the decimal variable (see next discussion for right
You should left adjust the value into the CHRINP variable. For
example, assume that in the previous example the 2 byte Quantity
variable contained X'050F'. To use MOVCHRDEC, the CHRINP variable
must be LEN(8). You can use CHGVAR to move the value to a LEN(8)
variable in which case the bytes are properly aligned and the new
variable will contain the value X'050F404040404040'. When you then
use MOVCHRDEC, the command will scan the character value from the
right for the first non-blank character and right adjust into the
numeric field. The DECOUT variable will contain X'000000000000050F'.
An error will occur if the field to be moved does not contain valid

DECOUT The decimal variable to contain the result. It must
be specified as LEN(15 0).
CHRINP The character variable to be moved. It must be
specified as LEN(8). The value placed in the
variable must be left adjusted.
