According to historical archives, Kasym started to develop the first Kyrgyz alphabet while a student at Kazinpros. His first screenplay written in Kyrgyz, in his alphabet, was for a theatrical performance called "Alymkul". It was performed several times during the summer of 1921 by students from Tashkent and Almaty. Unfortunately, the manuscript was lost after Kasym's arrest. Some of his poems and prose were published in Kazakh newspapers in Kyrgyz script since 1922. We therefore could assume that his alphabet was well known among Kyrgyz students living in Tashkent. T. Sydykbekov, a famous Kyrgyz writer, mentioned that Kasym's songs written in the new script were very popular among Kyrgyz youth.
