Darshan,

It's not clear for me, what do you want exactly ?
You want to remove the first character of a field no matter what ?

TRIMV will only remove the specified characters string. Normally used to remove leading or trailing spaces or a string pattern that exist almost everywhere

To remove the first character no matter which character is, you can use
EDIT(my_field, '$999999');

Where you put as many 9 as the number of character that you want to keep and the as many $ than character that you want to remove.
You can combine as you whish and can even replace character by other.
EDIT(my_field, '99$-9$/9999$9');

Sample
TABLE FILE CAR
PRINT COMPUTE NCAR1/A24 = EDIT(MODEL, '$99999999999999999999999');
      COMPUTE NCAR2/A24 = EDIT(MODEL, '99$-9$/9999$ 99999999999');
BY COUNTRY
BY CAR
END

EDIT function may be one of the options

Ensure that the number of 9's that you use in the EDIT command covers the length of field being edited, otherwise you'll miss some of the trailing data.

This also works fine

DEFINE FILE CAR
LENGTH/I2=ARGLEN(16,CAR,'I2');
LEAD_CHAR/A16=SUBSTV(LENGTH,CAR,2,LENGTH,LEAD_CHAR);
BY CAR
END
TABLE FILE CAR
PRINT LEAD_CHAR
BY CAR
END

Or we can use EDIT as Martin said.

DEFINE FILE CAR
LEAD_CHAR/A20=EDIT(CAR,'$999999999')
END
TABLE FILE CAR
PRINT LEAD_CHAR
BY CAR
END

In my experience, it's often better to use the new "Simplified * functions".

One reason being that they're agnostic to the lengths of the values they operate on, the other is that the non-simplified functions frequently cannot be translated to SQL.

That can cause performance issues when WF chooses to perform the function on the result-set it retrieves from the RDBMS instead of performing it there, especially when that resultset is significantly larger because the function cannot be used to limit the size of the set.

In this case, you're looking for: https://infocenter.information...s/source/topic76.htm

DEFINE FILE CAR
    CAR_TAIL/A16 = SUBSTRING(CAR, 2, 15);
END
TABLE FILE CAR
PRINT CAR_TAIL
BY CAR
END
