ABAP code to compare 7.40 inline data declaration with original syntax

The below ABAP code uses the older none in-line data declarations. This allows you to see the coding differences/benefits of the later inline syntax. It may also be useful if you are using an older version of SAP as some of the newer syntax above, such as the @DATA is not available until 4.70 EHP 8.

DATA:

ld_i_masdat
 
 TYPE FM_MASDAT_ID ,
ld_i_subnum
 
 TYPE FM_SUB_ID .


ld_i_masdat = 'Check type of data required'.
ld_i_subnum = 'Check type of data required'.
