To display content of internal table into ALV grid, use this method :
DATA : lo_table TYPE REF TO cl_salv_table.
* Create ALV
TRY.
cl_salv_table=>factory(
IMPORTING
r_salv_table = lo_table
CHANGING
t_table = gi_data_to_display ).
CATCH cx_salv_msg.
ENDTRY.
* Display ALV grid
lo_table->display( ).
Example of use in SAP demo program : SALV_DEMO_TABLE_REAL_SIMPLE.
DATA : lw_char10 TYPE char10,
lw_vbeln TYPE vbeln.
lw_char10 = '300841'.
UNPACK lw_char10 TO lw_vbeln. " ==> LW_VBELN = 0000300841
SHIFT lw_char LEFT DELETING LEADING '0'.
Several synthax below to do the same thing :
(Notice that you have to work with a field type CHAR to remove the ZERO, will not work with a NUMC variable)
DATA : li_tab TYPE TABLE OF trdir-name,
infotab TYPE t_varinfo OCCURS 0 WITH HEADER LINE.
CALL FUNCTION 'PRINT_SELECTIONS'
EXPORTING
mode = li_tab
rname = sy-repid "program name
rvariante = '' "variant name
TABLES
infotab = infotab.
LOOP AT infotab.
WRITE / infotab-line.
ENDLOOP.

User parameter ID table : USR05.
You can check if a Function Module exists into table TFDIR (field FUNCNAME).
You can also use code :
CALL FUNCTION 'FUNCTION_EXISTS'
