dear sir

i am trivikram, working as R&D engineer in efftronics systems,INDIA.
i have downloaded SDCC from net and using this compilerin my 8051 project
previously i had developed code in assembly for my proejct using another assembler
now i want write code in c for the present modules of project using SDCC
for this, first i need to convert my previous assembly code to get assembled in SDCC
because my assembler OBJECT CODE and SDCC object code cannot be linked
for this, i need assembler directives available in SDCC assembler
for example, .iftrue and .endif directives

i had searched in the documentation for these assembler directives
but didn't get the details
where i can get the list of directives and their details

i am waiting for ur reply sir

                  thanking u sir
with regards
